+ The logfile is where all logging and error messages are written. The logfile

- If no access settings are specified, the proxy talks to anyone that
- connects. If any access settings file are specified, then the proxy
- talks only to IP addresses permitted somewhere in this file and not

- The <quote>actionsfile</quote> is used to define what actions

- or rejected. The default file is in fact named <filename>actionsfile</filename>.
+ In this fictitious example, everything goes via an ISP's caching proxy,
+ except requests to that ISP:
</para>
<para>
- To determine which actions apply to a request, the URL of the request is
- compared to all patterns in this file. Every time it matches, the list of

</para>
<para>
- The matching of the domain part offers some flexible options: if the
- domain starts or ends with a dot, it becomes unanchored at that end.
- For example:
+ An advanced example for network administrators:
</para>
<para>
- <emphasis>.example.com</emphasis> - matches any domain that <emphasis>ENDS</emphasis> in
- <quote>.example.com</quote>.
+ If you have links to multiple ISPs that provide various special content to
+ their subscribers, you can configure forwarding to pass requests to the
+ specific host that's connected to that ISP so that everybody can see all
+ of the content on all of the ISPs.
</para>
<para>
- <emphasis>www.</emphasis> - matches any domain that <emphasis>STARTS</emphasis> with
- <quote>www</quote>.
+ This is a bit tricky, but here's an example:
</para>
+
<para>
- Additionally, there are wildcards that you can use in the domain names
- themselves. They work pretty similar to shell wildcards: <quote>*</quote>
- stands for zero or more arbitrary characters, <quote>?</quote> stands for
- any single character. And you can define charachter classes in square
- brackets and they can be freely mixed:
+ host-a has a PPP connection to isp-a.com. And host-b has a PPP connection to

- <quote>wwwz.example.com</quote>, etc., but <emphasis>not</emphasis>
- <quote>wwww.example.com</quote>.
+ Now, <emphasis>anyone</emphasis> on the Internet (including users on host-a

+<title>The Actions File</title>
+
+<para>
+ The <quote>default.action</quote> file (formerly
+ <filename>actionsfile</filename> or <filename>ijb.action</filename>) is used
+ to define what actions <application>Privoxy</application> takes, and thus
+ determines how ad images, cookies and various other aspects of HTTP content
+ and transactions are handled. These can be accepted or rejected for all
+ sites, or just those sites you choose. See below for a complete list of
+ actions.
+</para>
+<para>
+ Anything you want can blocked, including ads, banners, or just some obnoxious
+ URL that you would rather not see. Cookies can be accepted or rejected, or
+ accepted only during the current browser session (i.e. not written to disk).
+ Changes to <filename>default.action</filename> should be immediately visible
+ to <application>Privoxy</application> without the need to restart.
+</para>
+
+<para>
+ Note that some sites may misbehave, or possibly not work at all with some
+ actions. This may require some tinkering with the rules to get the most
+ mileage of <application>Privoxy's</application> features, and still be
+ able to see and enjoy just what you want to. There is no general rule of
+ thumb on these things. There just are too many variables, and sites are
+ always changing.
+
+</para>
+
+<para>
+ The easiest way to edit the <quote>actions</quote> file is with a browser by
+ loading <ulink url="http://p.p/">http://p.p/</ulink>, and then select
+ <quote>Edit Actions List</quote>. A text editor can also be used.
+</para>
+
+<para>
+ To determine which actions apply to a request, the URL of the request is
+ compared to all patterns in this file. Every time it matches, the list of
+ applicable actions for the URL is incrementally updated. You can trace
+ this process by visiting <ulink
+ url="http://p.p/show-url-info">http://p.p/show-url-info</ulink>.
+</para>
+
+
+<para>
+ There are four types of lines in this file: comments (begin with a
+ <quote>#</quote> character), actions, aliases and patterns, all of which are
+ explained below, as well as the configuration file syntax that
+ <application>Privoxy</application> understands.
+
+</para>
+
+
+<!-- ~~~~~ New section ~~~~~ -->
+<sect3>
+<title>URL Domain and Path Syntax</title>
+<para>
+ Generally, a pattern has the form <domain>/<path>, where both the
+ <domain> and <path> part are optional. If you only specify a
+ domain part, the <quote>/</quote> can be left out:
+</para>
+
+<para>
+ <emphasis>www.example.com</emphasis> - is a domain only pattern and will match any request to
+ <quote>www.example.com</quote>.
+</para>
+
+<para>
+ <emphasis>www.example.com/</emphasis> - means exactly the same.
+</para>
+
+<para>
+ <emphasis>www.example.com/index.html</emphasis> - matches only the single
+ document <quote>/index.html</quote> on <quote>www.example.com</quote>.
+</para>
+
+<para>
+ <emphasis>/index.html</emphasis> - matches the document <quote>/index.html</quote>,
+ regardless of the domain. So would match any page named <quote>index.html</quote>
+ on any site.
+</para>
+
+<para>
+ <emphasis>index.html</emphasis> - matches nothing, since it would be
+ interpreted as a domain name and there is no top-level domain called
+ <quote>.html</quote>.
+</para>
+
+<para>
+ The matching of the domain part offers some flexible options: if the
+ domain starts or ends with a dot, it becomes unanchored at that end.
+ For example:
+</para>
+
+<para>
+ <emphasis>.example.com</emphasis> - matches any domain or sub-domain that
+ <emphasis>ENDS</emphasis> in <quote>.example.com</quote>.
+</para>
+
+<para>
+ <emphasis>www.</emphasis> - matches any domain that <emphasis>STARTS</emphasis> with
+ <quote>www</quote>.
+</para>
+
+<para>
+ Additionally, there are wild-cards that you can use in the domain names
+ themselves. They work pretty similar to shell wild-cards: <quote>*</quote>
+ stands for zero or more arbitrary characters, <quote>?</quote> stands for
+ any single character. And you can define character classes in square
+ brackets and they can be freely mixed:
+</para>
+
+<para>
+ <emphasis>ad*.example.com</emphasis> - matches <quote>adserver.example.com</quote>,
+ <quote>ads.example.com</quote>, etc but not <quote>sfads.example.com</quote>.
+</para>
+
+<para>
+ <emphasis>*ad*.example.com</emphasis> - matches all of the above, and then some.
+</para>
+
+<para>
+ <emphasis>.?pix.com</emphasis> - matches <quote>www.ipix.com</quote>,
+ <quote>pictures.epix.com</quote>, <quote>a.b.c.d.e.upix.com</quote>, etc.
+</para>
+
+<para>
+ <emphasis>www[1-9a-ez].example.com</emphasis> - matches <quote>www1.example.com</quote>,
+ <quote>www4.example.com</quote>, <quote>wwwd.example.com</quote>,
+ <quote>wwwz.example.com</quote>, etc., but <emphasis>not</emphasis>
+ <quote>wwww.example.com</quote>.
+</para>
+
+<para>
+ If <application>Privoxy</application> was compiled with
+ <quote>pcre</quote> support (the default), Perl compatible regular expressions
+ can be used. These are more flexible and powerful than other types
+ of <quote>regular expressions</quote>. See the <filename>pcre/docs/</filename> directory or <quote>man
+ perlre</quote> (also available on <ulink
+ url="http://www.perldoc.com/perl5.6/pod/perlre.html">http://www.perldoc.com/perl5.6/pod/perlre.html</ulink>)
+ for details. A brief discussion of regular expressions is in the
+ <link linkend="regex">Appendix</link>. For instance:
+</para>
+
+<para>
+ <emphasis>/.*/advert[0-9]+\.jpe?g</emphasis> - would match a URL from any
+ domain, with any path that includes <quote>advert</quote> followed
+ immediately by one or more digits, then a <quote>.</quote> and ending in
+ either <quote>jpeg</quote> or <quote>jpg</quote>. So we match
+ <quote>example.com/ads/advert2.jpg</quote>, and
+ <quote>www.example.com/ads/banners/advert39.jpeg</quote>, but not
+ <quote>www.example.com/ads/banners/advert39.gif</quote> (no gifs in the
+ example pattern).
+</para>
+
+<para>
+ Please note that matching in the path is case
+ <emphasis>INSENSITIVE</emphasis> by default, but you can switch to case
+ sensitive at any point in the pattern by using the
+ <quote>(?-i)</quote> switch:
+</para>
+
+<para>
+ <emphasis>www.example.com/(?-i)PaTtErN.*</emphasis> - will match only
+ documents whose path starts with <quote>PaTtErN</quote> in
+ <emphasis>exactly</emphasis> this capitalization.

+ Regular expressions do essentially the same thing, but are much, much more
+ powerful. There are many more <quote>special characters</quote> and ways of
+ building complex patterns however. Let's look at a few of the common ones,
+ and then some examples:
</para>
+<simplelist>
+ <member>
+ <emphasis>.</emphasis> - Matches any single character, e.g. <quote>a</quote>,
+ <quote>A</quote>, <quote>4</quote>, <quote>:</quote>, or <quote>@</quote>.
+ </member>
+</simplelist>
+
+<simplelist>
+ <member>
+ <emphasis>?</emphasis> - The preceding character or expression is matched ZERO or ONE
+ times. Either/or.
+ </member>
+</simplelist>
+
+<simplelist>
+ <member>
+ <emphasis>+</emphasis> - The preceding character or expression is matched ONE or MORE
+ times.
+ </member>
+</simplelist>
+
+<simplelist>
+ <member>
+ <emphasis>*</emphasis> - The preceding character or expression is matched ZERO or MORE
+ times.
+ </member>
+</simplelist>
+
+<simplelist>
+ <member>
+ <emphasis>\</emphasis> - The <quote>escape</quote> character denotes that
+ the following character should be taken literally. This is used where one of the
+ special characters (e.g. <quote>.</quote>) needs to be taken literally and
+ not as a special meta-character.
+ </member>
+</simplelist>
+
+<simplelist>
+ <member>
+ <emphasis>[]</emphasis> - Characters enclosed in brackets will be matched if
+ any of the enclosed characters are encountered.
+ </member>
+</simplelist>
+
+<simplelist>
+ <member>
+ <emphasis>()</emphasis> - parentheses are used to group a sub-expression,
+ or multiple sub-expressions.
+ </member>
+</simplelist>
+
+<simplelist>
+ <member>
+ <emphasis>|</emphasis> - The <quote>bar</quote> character works like an
+ <quote>or</quote> conditional statement. A match is successful if the
+ sub-expression on either side of <quote>|</quote> matches.
+ </member>
+</simplelist>
+
+<simplelist>
+ <member>
+ <emphasis>s/string1/string2/g</emphasis> - This is used to rewrite strings of text.
+ <quote>string1</quote> is replaced by <quote>string2</quote> in this
+ example.
+ </member>
+</simplelist>
+
<para>
- Now some URLs that we want <quote>blocked</quote>, ie we won't see them.
- Many of these use regular expressions that will expand to match multiple
- URLs:
+ These are just some of the ones you are likely to use when matching URLs with
+ <application>Privoxy</application>, and is a long way from a definitive
+ list. This is enough to get us started with a few simple examples which may
+ be more illuminating:

+ <emphasis><literal>/.*/banners/.*</literal></emphasis> - A simple example
+ that uses the common combination of <quote>.</quote> and <quote>*</quote> to
+ denote any character, zero or more times. In other words, any string at all.
+ So we start with a literal forward slash, then our regular expression pattern
+ (<quote>.*</quote>) another literal forward slash, the string
+ <quote>banners</quote>, another forward slash, and lastly another
+ <quote>.*</quote>. We are building
+ a directory path here. This will match any file with the path that has a
+ directory named <quote>banners</quote> in it. The <quote>.*</quote> matches
+ any characters, and this could conceivably be more forward slashes, so it
+ might expand into a much longer looking path. For example, this could match:
+ <quote>/eye/hate/spammers/banners/annoy_me_please.gif</quote>, or just
+ <quote>/banners/annoying.html</quote>, or almost an infinite number of other
+ possible combinations, just so it has <quote>banners</quote> in the path
+ somewhere.

- Custom <quote>actions</quote>, known to <application>Junkbuster</application>
- as <quote>aliases</quote>, can be defined by combining other <quote>actions</quote>.
- These can in turn be invoked just like the built-in <quote>actions</quote>.
- Currently, an alias can contain any character except space, tab, <quote>=</quote>,
- <quote>{</quote> or <quote>}</quote>. But please use only <quote>a</quote>-
- <quote>z</quote>, <quote>0</quote>-<quote>9</quote>, <quote>+</quote>, and
- <quote>-</quote>. Alias names are not case sensitive, and
- <emphasis>must be defined before anything</emphasis> else in
- <filename>actionsfile</filename>! And there can only be one set of
- <quote>aliases</quote> of defined.
+ A now something a little more complex:
</para>
<para>
- Now let's define a few aliases:
+ <emphasis><literal>/.*/adv((er)?ts?|ertis(ing|ements?))?/</literal></emphasis> -
+ We have several literal forward slashes again (<quote>/</quote>), so we are
+ building another expression that is a file path statement. We have another
+ <quote>.*</quote>, so we are matching against any conceivable sub-path, just so
+ it matches our expression. The only true literal that <emphasis>must
+ match</emphasis> our pattern is <application>adv</application>, together with
+ the forward slashes. What comes after the <quote>adv</quote> string is the
+ interesting part.
</para>
<para>
- <literal>

- <literallayout>
- # Useful customer aliases we can use later. These must come first!
- {{alias}}
- +no-cookies = +no-cookies-set +no-cookies-read

- fragile = -block -no-cookies -filter -fast-redirects -hide-referer -no-popups
- shop = -no-cookies -filter -fast-redirects
- +imageblock = +block +image
+ Remember the <quote>?</quote> means the preceding expression (either a
+ literal character or anything grouped with <quote>(...)</quote> in this case)
+ can exist or not, since this means either zero or one match. So
+ <quote>((er)?ts?|ertis(ing|ements?))</quote> is optional, as are the
+ individual sub-expressions: <quote>(er)</quote>,
+ <quote>(ing|ements?)</quote>, and the <quote>s</quote>. The <quote>|</quote>
+ means <quote>or</quote>. We have two of those. For instance,
+ <quote>(ing|ements?)</quote>, can expand to match either <quote>ing</quote>
+ <emphasis>OR</emphasis> <quote>ements?</quote>. What is being done here, is an
+ attempt at matching as many variations of <quote>advertisement</quote>, and
+ similar, as possible. So this would expand to match just <quote>adv</quote>,
+ or <quote>advert</quote>, or <quote>adverts</quote>, or
+ <quote>advertising</quote>, or <quote>advertisement</quote>, or
+ <quote>advertisements</quote>. You get the idea. But it would not match
+ <quote>advertizements</quote> (with a <quote>z</quote>). We could fix that by
+ changing our regular expression to:
+ <quote>/.*/adv((er)?ts?|erti(s|z)(ing|ements?))?/</quote>, which would then match
+ either spelling.

+<para>
+ <emphasis><literal>/.*/advert[0-9]+\.(gif|jpe?g)</literal></emphasis> - Again
+ another path statement with forward slashes. Anything in the square brackets
+ <quote>[]</quote> can be matched. This is using <quote>0-9</quote> as a
+ shorthand expression to mean any digit one through nine. It is the same as
+ saying <quote>0123456789</quote>. So any digit matches. The <quote>+</quote>
+ means one or more of the preceding expression must be included. The preceding
+ expression here is what is in the square brackets -- in this case, any digit
+ one through nine. Then, at the end, we have a grouping: <quote>(gif|jpe?g)</quote>.
+ This includes a <quote>|</quote>, so this needs to match the expression on
+ either side of that bar character also. A simple <quote>gif</quote> on one side, and the other
+ side will in turn match either <quote>jpeg</quote> or <quote>jpg</quote>,
+ since the <quote>?</quote> means the letter <quote>e</quote> is optional and
+ can be matched once or not at all. So we are building an expression here to
+ match image GIF or JPEG type image file. It must include the literal
+ string <quote>advert</quote>, then one or more digits, and a <quote>.</quote>
+ (which is now a literal, and not a special character, since it is escaped
+ with <quote>\</quote>), and lastly either <quote>gif</quote>, or
+ <quote>jpeg</quote>, or <quote>jpg</quote>. Some possible matches would
+ include: <quote>//advert1.jpg</quote>,
+ <quote>/nasty/ads/advert1234.gif</quote>,
+ <quote>/banners/from/hell/advert99.jpg</quote>. It would not match
+ <quote>advert1.gif</quote> (no leading slash), or
+ <quote>/adverts232.jpg</quote> (the expression does not include an
+ <quote>s</quote>), or <quote>/advert1.jsp</quote> (<quote>jsp</quote> is not
+ in the expression anywhere).
</para>
<para>
- Some examples using our <quote>shop</quote> and <quote>fragile</quote>
- aliases from above:
+ <emphasis><literal>s/microsoft(?!.com)/MicroSuck/i</literal></emphasis> - This is
+ a substitution. <quote>MicroSuck</quote> will replace any occurrence of
+ <quote>microsoft</quote>. The <quote>i</quote> at the end of the expression
+ means ignore case. The <quote>(?!.com)</quote> means
+ the match should fail if <quote>microsoft</quote> is followed by
+ <quote>.com</quote>. In other words, this acts like a <quote>NOT</quote>
+ modifier. In case this is a hyperlink, we don't want to break it ;-).

+ The way <application>Privoxy</application> applies <quote>actions</quote>
+ and <quote>filters</quote> to any given URL can be complex, and not always so
+ easy to understand what is happening. And sometimes we need to be able to
+ <emphasis>see</emphasis> just what <application>Privoxy</application> is
+ doing. Especially, if something <application>Privoxy</application> is doing
+ is causing us a problem inadvertantly. It can be a little daunting to look at
+ the actions and filters files themselves, since they tend to be filled with
+ <quote>regular expressions</quote> whose consequences are not always
+ so obvious. <application>Privoxy</application> provides the
+ <ulink url="http://config.privoxy.org/show-url-info">http://config.privoxy.org/show-url-info</ulink>
+ page that can show us very specifically how <application>actions</application>
+ are being applied to any given URL. This is a big help for troubleshooting.

- Archives are available here too.
+ First, enter one URL (or partial URL) at the prompt, and then
+ <application>Privoxy</application> will tell us
+ how the current configuration will handle it. This will not
+ help with filtering effects from the <filename>default.filter</filename> file! It
+ also will not tell you about any other URLs that may be embedded within the
+ URL you are testing. For instance, images such as ads are expressed as URLs
+ within the raw page source of HTML pages. So you will only get info for the
+ actual URL that is pasted into the prompt area -- not any sub-URLs. If you
+ want to know about embedded URLs like ads, you will have to dig those out of
+ the HTML source. Use your browser's <quote>View Page Source</quote> option
+ for this. Or right click on the ad, and grab the URL.

-<title>History</title>
<para>
- <application>Junkbuster</application> was originally written by Anonymous
- Coders and <ulink
- url="http://www.junkbusters.com/ht/en/ijbfaq.html">JunkBusters
- Corporation</ulink>, and was released as free open-source software under the
- GNU GPL. <ulink url="http://www.waldherr.org/junkbuster/">Stefan
- Waldherr</ulink> made many improvements, and started the <ulink
- url="http://sourceforge.net/projects/ijbswa/">SourceForge project</ulink> to
- rekindle development. The last stable release was v2.0.2, which has now
- grown whiskers ;-).
+ This is much more informative, and tells us how we have defined our
+ <quote>actions</quote>, and which ones match for our example,
+ <quote>google.com</quote>. The first grouping shows our default
+ settings, which would apply to all URLs. If you look at your <quote>actions</quote>
+ file, this would be the section just below the <quote>aliases</quote> section
+ near the top. This applies to all URLs as signified by the single forward
+ slash -- <quote>/</quote>.
+
</para>
-</sect2>
+<para>
+ These are the default actions we have enabled. But we can define additional
+ actions that would be exceptions to these general rules, and then list
+ specific URLs that these exceptions would apply to. Last match wins.
+ Just below this then are two explict matches for <quote>.google.com</quote>.
+ The first is negating our various cookie blocking actions (i.e. we will allow
+ cookies here). The second is allowing <quote>fast-redirects</quote>. Note
+ that there is a leading dot here -- <quote>.google.com</quote>. This will
+ match any hosts and sub-domains, in the google.com domain also, such as
+ <quote>www.google.com</quote>. So, apparently, we have these actions defined
+ somewhere in the lower part of our actions file, and
+ <quote>google.com</quote> is referenced in these sections.

-<title>Regular Expressions</title>
-<para>
- <application>Junkbuster</application> can use <quote>regular expressions</quote>
- in various config files. Assuming support for <quote>pcre</quote> (Perl
- Compatible Regular Expressions) is compiled in, which is the default. Such
- configuration directives do not require regular expressions, but they can be
- used to increase flexibility by matching a pattern with wildcards against
- URLs.
+ </screen>
</para>
<para>
- If you are reading this, you probably don't understand what <quote>regular
- expressions</quote> are, or what they can do. So this will be a very brief
- introduction only. A full explanation would require a book ;-)
+ Now another example, <quote>ad.doubleclick.net</quote>:
</para>
<para>
- <quote>Regular expressions</quote> is a way of matching one character
- expression against another to see if it matches or not. One of the
- <quote>expressions</quote> is a literal string of readable characters
- (letter, numbers, etc), and the other is a complex string of literal
- characters combined with wildcards, and other special characters, called
- metacharacters. The <quote>metacharacters</quote> have special meanings and
- are used to build the complex pattern to be matched against. Perl Compatible
- Regular Expressions is an enhanced form of the regular expression language
- with backward compatibility.
+ <screen>
+
+ { +block +image }
+ .ad.doubleclick.net
+
+ { +block +image }
+ ad*.
+
+ { +block +image }
+ .doubleclick.net
+
+ </screen>
</para>
<para>
- To make a simple analogy, we do something similar when we use wildcard
- characters when listing files with the <command>dir</command> command in DOS.
- <literal>*.*</literal> matches all filenames. The <quote>special</quote>
- character here is the asterik which matches any and all characters. We can be
- more specific and use <literal>?</literal> to match just individual
- characters. So <quote>dir file?.text</quote> would match
- <quote>file1.txt</quote>, <quote>file2.txt</quote>, etc. We are pattern
- matching, using a similar technique to <quote>regular expressions</quote>!
+ We'll just show the interesting part here, the explicit matches. It is
+ matched three different times. Each as an <quote>+block +image</quote>,
+ which is the expanded form of one of our aliases that had been defined as:
+ <quote>+imageblock</quote>. (<quote>Aliases</quote> are defined in the
+ first section of the actions file and typically used to combine more
+ than one action.)
</para>
<para>
- Regular expressions do essentially the same thing, but are much, much more
- powerful. There are many more <quote>special characters</quote> and ways of
- building complex patterns however. Let's look at a few of the common ones,
- and then some examples:
+ Any one of these would have done the trick and blocked this as an unwanted
+ image. This is unnecessarily redundant since the last case effectively
+ would also cover the first. No point in taking chances with these guys
+ though ;-) Note that if you want an ad or obnoxious
+ URL to be invisible, it should be defined as <quote>ad.doubleclick.net</quote>
+ is done here -- as both a <quote>+block</quote> <emphasis>and</emphasis> an
+ <quote>+image</quote>. The custom alias <quote>+imageblock</quote> does this
+ for us.

+ block (-block) pages with <quote>adsl</quote>. There are various ways to

+</para>
<para>
- These are just some of the ones you are likely to use when matching URLs with
- <application>Junkbuster</application>, and is a long way from a definitive
- list. This is enough to get us started with a few simple examples which may
- be more illuminating:
+ <screen>
+
+ { -block }
+ /adsl
+
+ </screen>
</para>
<para>
- <emphasis><literal>/.*/banners/.*</literal></emphasis> - A simple example
- that uses the common combination of <quote>.</quote> and <quote>*</quote> to
- denote any character, zero or more times. In other words, any string at all.
- So we start with a literal forward slash, then our regular expression pattern
- (<quote>.*</quote>) another literal forward slash, the string
- <quote>banners</quote>, another forward slash, and lastly another
- <quote>.*</quote>. We are building
- a directory path here. This will match any file with the path that has a
- directory named <quote>banners</quote> in it. The <quote>.*</quote> matches
- any characters, and this could conceivably be more forward slashes, so it
- might expand into a much longer looking path. For example, this could match:
- <quote>/eye/hate/spammers/banners/annoy_me_please.gif</quote>, or just
- <quote>/banners/annoying.html</quote>, or almost an infinite number of other
- possible combinations, just so it has <quote>banners</quote> in the path
- somewhere.
+ Now the page displays ;-) Be sure to flush your browser's caches when
+ making such changes. Or, try using <literal>Shift+Reload</literal>.
</para>
<para>
- A now something a little more complex:
+ But now what about a situation where we get no explicit matches like
+ we did with:
</para>
<para>
- <emphasis><literal>/.*/adv((er)?ts?|ertis(ing|ements?))?/</literal></emphasis> -
- We have several literal forward slashes again (<quote>/</quote>), so we are
- building another expression that is a file path statement. We have another
- <quote>.*</quote>, so we are matching against any conceivable sub-path, just so
- it matches our expression. The only true literal that <emphasis>must
- match</emphasis> our pattern is <application>adv</application>, together with
- the forward slashes. What comes after the <quote>adv</quote> string is the
- interesting part.
+ <screen>
+
+ { -block }
+ /adsl
+
+ </screen>
</para>
<para>
- Remember the <quote>?</quote> means the preceding expression (either a
- literal character or anything grouped with <quote>(...)</quote> in this case)
- can exist or not, since this means either zero or one match. So
- <quote>((er)?ts?|ertis(ing|ements?))</quote> is optional, as are the
- individual sub-expressions: <quote>(er)</quote>,
- <quote>(ing|ements?)</quote>, and the <quote>s</quote>. The <quote>|</quote>
- means <quote>or</quote>. We have two of those. For instance,
- <quote>(ing|ements?)</quote>, can expand to match either <quote>ing</quote>
- <emphasis>OR</emphasis> <quote>ements?</quote>. What is being done here, is an
- attempt at matching as many variations of <quote>advertisement</quote>, and
- similar, as possible. So this would expand to match just <quote>adv</quote>,
- or <quote>advert</quote>, or <quote>adverts</quote>, or
- <quote>advertising</quote>, or <quote>advertisement</quote>, or
- <quote>advertisements</quote>. You get the idea. But it would not match
- <quote>advertizements</quote> (with a <quote>z</quote>). We could fix that by
- changing our regular expression to:
- <quote>/.*/adv((er)?ts?|erti(s|z)(ing|ements?))?/</quote>, which would then match
- either spelling.
+ That actually was very telling and pointed us quickly to where the problem
+ was. If you don't get this kind of match, then it means one of the default
+ rules in the first section is causing the problem. This would require some
+ guesswork, and maybe a little trial and error to isolate the offending rule.
+ One likely cause would be one of the <quote>{+filter}</quote> actions. Try
+ adding the URL for the site to one of aliases that turn off <quote>+filter</quote>:
</para>
<para>
- <emphasis><literal>/.*/advert[0-9]+\.(gif|jpe?g)</literal></emphasis> - Again
- another path statement with forward slashes. Anything in the square brackets
- <quote>[]</quote> can be matched. This is using <quote>0-9</quote> as a
- shorthand expression to mean any digit one through nine. It is the same as
- saying <quote>0123456789</quote>. So any digit matches. The <quote>+</quote>
- means one or more of the preceding expression must be included. The preceding
- expression here is what is in the square brackets -- in this case, any digit
- one through nine. Then, at the end, we have a grouping: <quote>(gif|jpe?g)</quote>.
- This includes a <quote>|</quote>, so this needs to match the expression on
- either side of that bar character also. A simple <quote>gif</quote> on one side, and the other
- side will in turn match either <quote>jpeg</quote> or <quote>jpg</quote>,
- since the <quote>?</quote> means the letter <quote>e</quote> is optional and
- can be matched once or not at all. So we are building an expression here to
- match image GIF or JPEG type image file. It must include the literal
- string <quote>advert</quote>, then one or more digits, and a <quote>.</quote>
- (which is now a literal, and not a special character, since it is escaped
- with <quote>\</quote>), and lastly either <quote>gif</quote>, or
- <quote>jpeg</quote>, or <quote>jpg</quote>. Some possible matches would
- include: <quote>//advert1.jpg</quote>,
- <quote>/nasty/ads/advert1234.gif</quote>,
- <quote>/banners/from/hell/advert99.jpg</quote>. It would not match
- <quote>advert1.gif</quote> (no leading slash), or
- <quote>/adverts232.jpg</quote> (the expression does not include an
- <quote>s</quote>), or <quote>/advert1.jsp</quote> (<quote>jsp</quote> is not
- in the expression anywhere).

- <emphasis><literal>s/microsoft(?!.com)/MicroSuck/i</literal></emphasis> - This is
