If you would like to build binary images on OS/2 yourself, you will need
- a working EMX/GCC environment, plus several Unix-like tools. The Hobbes
- OS/2 archive is a good place to start when building such an environment.
- A set of Unix-like tools named gnupack is located here:
- <ulink url="http://hobbes.nmsu.edu/cgi-bin/h-search?sh=1&key=gnupack&stype=all&sort=type&dir=%2Fpub%2Fos2%2Fapps">http://hobbes.nmsu.edu/cgi-bin/h-search?sh=1&key=gnupack&stype=all&sort=type&dir=%2Fpub%2Fos2%2Fapps</ulink>

-<para>
- Once you have the source code unpacked as above, you can build the binaries
- from the <filename>current/</filename> directory:
+ 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
+ <function>select()</function> socket call.

+ </screen>
+ This will create a directory named os2setup/, which will contain the
+ <filename>Makefile.vac</filename> makefile and <filename>os2build.cmd</filename>
+ which is used to completely create the binary distribution. The sequence

+ <screen>
+ cd current

autoconf
sh configure
- make
+ cd ..\os2setup

<para>
- Again, the main configuration file is named <filename>config</filename> on
- Linux/Unix/BSD and OS/2, and <filename>junkbustr.txt</filename> on Windows.
- Configuration lines consist of an initial keyword followed by a list of
- values, all separated by whitespace (any number of spaces or tabs). For
- example:
+ 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
+ command line and no default configuration file can be found,
+ <application>Privoxy</application> will fail to start.
</para>
+
<para>
- <literal>
- <MSGText>
- <literallayout>
- <emphasis>blockfile blocklist.ini</emphasis>
- </literallayout>
- </MSGText>
- </literal>
+ The included default configuration files should give a reasonable starting
+ point, though may be somewhat aggressive in blocking junk. Most of the
+ per site configuration is done in the <quote>actions</quote> files. These
+ are where various cookie actions are defined, ad and banner blocking,
+ and other aspects of <application>Privoxy</application> configuration. There
+ are several such files included, with varying levels of aggressiveness.
</para>
<para>
- Indicates that the blockfile is named <quote>blocklist.ini</quote>.
+ You will probably want to keep an eye out for sites that require persistent
+ cookies, and add these to <filename>default.action</filename> as needed. By
+ default, most of these will be accepted only during the current browser
+ session, until you add them to 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 browser(s)
+ should be set to accept all cookies.
</para>
<para>
- The <quote><literal>#</literal></quote> indicates a comment. Any part of a
- line following a <quote><literal>#</literal></quote> is ignored, except if
- the <quote><literal>#</literal></quote> is preceded by a
- <quote><literal>\</literal></quote>.
+ <application>Privoxy</application> is HTTP/1.1 compliant, but not all 1.1
+ features are as yet implemented. If browsers that support HTTP/1.1 (like
+ <application>Mozilla</application> or recent versions of I.E.) experience
+ problems, you might try to force HTTP/1.0 compatibility. For Mozilla, look
+ under <literal>Edit -> Preferences -> Debug -> Networking</literal>.
+ Or set the <quote>+downgrade</quote> config option in
+ <filename>default.action</filename>.
</para>
<para>
- Thus, by placing a <quote><literal>#</literal></quote> at the start of an
- existing configuration line, you can make it a comment and it will be treated
- as if it weren't there. This is called <quote>commenting out</quote> an
- option and can be useful to turn off features: If you comment out the
- <quote>logfile</quote> line, <application>junkbuster</application> will not
- log to a file at all. Watch for the <quote>default:</quote> section in each
- explanation to see what happens if the option is left unset (or commented
- out).
+ 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://p.p/">http://p.p/</ulink>,
+ and then follow the link to <quote>edit the actions list</quote>.
+ (This is an internal page and does not require Internet access.)
</para>
<para>
- Long lines can be continued on the next line by using a
- <quote><literal>\</literal></quote> as the very last character.
+ In fact, various aspects of <application>Privoxy</application>

+<title>The Main Configuration File</title>
+<para>
+ Again, the main configuration file is named <filename>config</filename> on
+ Linux/Unix/BSD and OS/2, and <filename>config.txt</filename> on Windows.
+ Configuration lines consist of an initial keyword followed by a list of
+ values, all separated by whitespace (any number of spaces or tabs). For
+ example:
+</para>
+
+<para>
+ <literal>
+ <msgtext>
+ <literallayout>
+ <emphasis>blockfile blocklist.ini</emphasis>
+ </literallayout>
+ </msgtext>

+</para>
+
+<para>
+ Indicates that the blockfile is named <quote>blocklist.ini</quote>. (A
+ default installation does not use this.)
+</para>
+
+<para>
+ A <quote><literal>#</literal></quote> indicates a comment. Any part of a
+ line following a <quote><literal>#</literal></quote> is ignored, except if
+ the <quote><literal>#</literal></quote> is preceded by a
+ <quote><literal>\</literal></quote>.
+</para>
+
+<para>
+ Thus, by placing a <quote><literal>#</literal></quote> at the start of an
+ existing configuration line, you can make it a comment and it will be treated
+ as if it weren't there. This is called <quote>commenting out</quote> an
+ option and can be useful to turn off features: If you comment out the
+ <quote>logfile</quote> line, <application>Privoxy</application> will not
+ log to a file at all. Watch for the <quote>default:</quote> section in each
+ explanation to see what happens if the option is left unset (or commented
+ out).
+</para>
+
+<para>
+ Long lines can be continued on the next line by using a
+ <quote><literal>\</literal></quote> as the very last character.

+<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 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.
+ </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. 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}

+ -hide-user-agent -image +image-blocker{blank} +no-compression

+ -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 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.
+
+</para>
+
+<para>
+ And now we pull it altogether in the bottom section and summarize how
+ <application>Privoxy</application> is appying all its <quote>actions</quote>
+ to <quote>google.com</quote>:
+
+</para>
+
+<para>
+ <screen>
+
+ Final results:
+
+ -add-header -block -deanimate-gifs -downgrade -fast-redirects

+ +filter{webbugs} +filter{nimda} +filter{banners-by-size} +filter{hal}

+

+</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>
+

+ 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 explictly 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.
