+<title>Anatomy of an Action</title>
+
+<para>
+ The way <application>Privoxy</application> applies <quote>actions</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 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.

+
+<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 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{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} -limit-connect +no-compression
+ -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}
+ +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 }
+ /
+
+ { +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 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 ;-)
+
+</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>
