<para>
- To install, of course:
+ If no configuration file is specified on the command line,
+ <application>Privoxy</application> will look for a file named
+ <filename>config</filename> in the current directory. Except on Win32 where
+ it will try <filename>config.txt</filename>. If no file is specified on the

+ configuration. If you want the browser to handle this instead, you will need
+ to edit <filename>default.action</filename> and disable this feature. If you
+ use more than one browser, it would make more sense to let
+ <application>Privoxy</application> handle this. In which case, the

<para>
- <application>Junkbuster</application> is packaged in a WarpIN self-
- installing archive. The self-installing program will be named depending
- on the release version, something like:
- <filename>ijbos2_setup_1.2.3.exe</filename>. In order to install it, simply
- run this executable or double-click on its icon and follow the WarpIN
- installation panels. A shadow of the <application>Junkbuster</application>
- executable will be placed in your startup folder so it will start
- automatically whenever OS/2 starts.
+ Another feature where you will probably want to define exceptions for trusted
+ sites is the popup-killing (through the <literal>+popup</literal> and
+ <literal>+filter{popups}</literal> actions), because your favorite shopping,
+ banking, or leisure site may need popups.
</para>
<para>
- The directory you choose to install <application>Junkbuster</application>
- into will contain all of the configuration files.
+ <application>Privoxy</application> is HTTP/1.1 compliant, but not all of
+ the optional 1.1 features are as yet supported. In the unlikely event that
+ you experience inexplicable problems with browsers that use HTTP/1.1 per default
+ (like <application>Mozilla</application> or recent versions of I.E.), you might
+ try to force HTTP/1.0 compatibility. For Mozilla, look under <literal>Edit ->
+ Preferences -> Debug -> Networking</literal>.
+ Alternatively, set the <quote>+downgrade</quote> config option in
+ <filename>default.action</filename> which will downgrade your browser's HTTP
+ requests from HTTP/1.1 to HTTP/1.0 before processing them.
</para>
<para>
- If you would like to build binary images on OS/2 yourself, you will need
- a few Unix-like tools: autoconf, autoheader and sh. These tools will be
- used to create the required config.h file, which is not part of the
- source distribution because it differs based on platform. You will also
- need a compiler.
- The distribution has been created using IBM VisualAge compilers, but you
- can use any compiler you like. GCC/EMX has the disadvantage of needing
- to be single-threaded due to a limitation of EMX's implementation of the
- select() socket call.
+ After running <application>Privoxy</application> for a while, you can
+ start to fine tune the configuration to suit your personal, or site,
+ preferences and requirements. There are many, many aspects that can
+ be customized. <quote>Actions</quote> (as specified in <filename>default.action</filename>)
+ can be adjusted by pointing your browser to
+ <ulink url="http://config.privoxy.org/">http://config.privoxy.org/</ulink>
+ (shortcut: <ulink url="http://p.p/">http://p.p/</ulink>),
+ and then follow the link to <quote>edit the actions list</quote>.

- To determine which actions apply to a request, the URL of the request is

+ Note that some actions like cookie suppression or script disabling may
+ render some sites unusable, which rely on these techniques to work properly.
+ Finding the right mix of actions is not easy and certainly a matter of personal
+ taste. In general, it can be said that the more <quote>aggressive</quote>
+ your default settings (in the top section of the actions file) are,
+ the more exceptions for <quote>trusted</quote> sites you will have to

+<title>Anatomy of an Action</title>
+
+<para>
+ 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 inadvertently. 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.
+ </para>
+
+<para>
+ 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 (i.e. a web page). 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.
+</para>
+
+<para>
+ Let's look at an example, <ulink url="http://google.com">google.com</ulink>,
+ one section at a time:
+</para>
+
+<para>
+ <screen>
+ System default actions:
+
+ { -add-header -block -deanimate-gifs -downgrade -fast-redirects -filter
+ -hide-forwarded -hide-from -hide-referer -hide-user-agent -image
+ -image-blocker -limit-connect -no-compression -no-cookies-keep
+ -no-cookies-read -no-cookies-set -no-popups -vanilla-wafer -wafer }
+
+ </screen>
+</para>
+
+<para>
+ This is the top section, and only tells us of the compiled in defaults. This
+ is basically what <application>Privoxy</application> would do if there
+ were not any <quote>actions</quote> defined, i.e. it does nothing. Every action
+ is disabled. This is not particularly informative for our purposes here. OK,
+ next section:
+</para>
+
+<para>
+ <screen>
+
+ Matches for http://google.com:
+
+ { -add-header -block +deanimate-gifs -downgrade +fast-redirects
+ +filter{html-annoyances} +filter{js-annoyances} +filter{no-popups}
+ +filter{webbugs} +filter{nimda} +filter{banners-by-size} +filter{hal}
+ +filter{fun} +hide-forwarded +hide-from{block} +hide-referer{forge}
+ -hide-user-agent -image +image-blocker{blank} +no-compression
+ +no-cookies-keep -no-cookies-read -no-cookies-set +no-popups
+ -vanilla-wafer -wafer }
+ /
+
+ { -no-cookies-keep -no-cookies-read -no-cookies-set }
+ .google.com
+
+ { -fast-redirects }
+ .google.com
+
+ </screen>
+</para>
+
+<para>
+ 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>
+
+<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 explicit 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.
+
+</para>
+
+<para>
+ And now we pull it altogether in the bottom section and summarize how
+ <application>Privoxy</application> is applying all its <quote>actions</quote>
+ to <quote>google.com</quote>:
+
+</para>
+
+<para>
+ <screen>
+
+ Final results:
+
+ -add-header -block -deanimate-gifs -downgrade -fast-redirects
+ +filter{html-annoyances} +filter{js-annoyances} +filter{no-popups}
+ +filter{webbugs} +filter{nimda} +filter{banners-by-size} +filter{hal}

+ -no-cookies-keep -no-cookies-read -no-cookies-set +no-popups -vanilla-wafer
+ -wafer
+
+ </screen>
+</para>
+
+<para>
+ Now another example, <quote>ad.doubleclick.net</quote>:
+</para>
+
+<para>
+ <screen>
+
+ { +block +image }
+ .ad.doubleclick.net
+
+ { +block +image }
+ ad*.
+
+ { +block +image }
+ .doubleclick.net
+
+ </screen>
+</para>
+
+<para>
+ 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>
+ 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.
+</para>
+
+<para>
+ One last example. Let's try <quote>http://www.rhapsodyk.net/adsl/HOWTO/</quote>.
+ This one is giving us problems. We are getting a blank page. Hmmm...
+</para>
+
+<para>
+ <screen>
+
+ Matches for http://www.rhapsodyk.net/adsl/HOWTO/:
+
+ { -add-header -block +deanimate-gifs -downgrade +fast-redirects
+ +filter{html-annoyances} +filter{js-annoyances} +filter{no-popups}
+ +filter{webbugs} +filter{nimda} +filter{banners-by-size} +filter{hal}

+ /
+
+ { +block +image }
+ /ads
+
+ </screen>
+</para>
+
+<para>
+ Ooops, the <quote>/adsl/</quote> is matching <quote>/ads</quote>! But
+ we did not want this at all! Now we see why we get the blank page. We could
+ now add a new action below this that explicitly does <emphasis>not</emphasis>
+ block (-block) pages with <quote>adsl</quote>. There are various ways to
+ handle such exceptions. Example:
+</para>
+
+<para>
+ <screen>
+
+ { -block }
+ /adsl
+
+ </screen>
+</para>
+
+<para>
+ 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>
+ But now what about a situation where we get no explicit matches like
+ we did with:
+</para>
+
+<para>
+ <screen>
+
+ { -block }
+ /adsl
+
+ </screen>
+</para>
+
+<para>
+ 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>
+ <screen>
+
+ {shop}
+ .quietpc.com
+ .worldpay.com # for quietpc.com
+ .jungle.com
+ .scan.co.uk
+ .forbes.com
+
+ </screen>
+</para>
+
+<para>
+ <quote>{shop}</quote> is an <quote>alias</quote> that expands to
+ <quote>{ -filter -no-cookies -no-cookies-keep }</quote>. Or you could do
+ your own exception to negate filtering:
+
+</para>
+
+<para>
+ <screen>
+
+ {-filter}
+ .forbes.com
+
+ </screen>
+</para>
+
+<para>
+ <quote>{fragile}</quote> is an alias that disables most actions. This can be
+ used as a last resort for problem sites. Remember to flush caches! If this
+ still does not work, you will have to go through the remaining actions one by
+ one to find which one(s) is causing the problem.
