+<title>Quickstart to Ad Blocking</title>
+<!--
+ NOTE: This section is deliberately redundant for those that don't
+ want to read the whole thing (which is getting lengthy).
+-->
+<para>
+ Ad blocking is but one of <application>Privoxy's</application>
+ array of features. Many of these features are for the technically minded advanced
+ user. But, ad and banner blocking is surely common ground for everybody.
+</para>
+<para>
+ This section will provide a quick summary of ad blocking so
+ you can get up to speed quickly without having to read the more extensive
+ information provided below, though this is highly recommended.
+</para>
+<para>
+ First a bit of a warning ... blocking ads is much like blocking SPAM: the
+ more aggressive you are about it, the more likely you are to block
+ things that were not intended. So there is a trade off here. If you want
+ extreme ad free browsing, be prepared to deal with more
+ <quote>problem</quote> sites, and to spend more time adjusting the
+ configuration to solve these unintended consequences. In short, there is
+ not an easy way to eliminate <emphasis>all</emphasis> ads. Either take
+ the easy way and settle for <emphasis>most</emphasis> ads blocked with the
+ default configuration, or jump in and tweak it for your personal surfing
+ habits and preferences.
+</para>
+<para>
+ Secondly, a brief explanation of <application>Privoxy's </application>
+ <quote>actions</quote>. <quote>Actions</quote> in this context, are
+ the directives we use to tell <application>Privoxy</application> to perform
+ some task relating to HTTP transactions (i.e. web browsing). We tell
+ <application>Privoxy</application> to take some <quote>action</quote>. Each
+ action has a unique name and function. While there are many potential
+ <application>actions</application> in <application>Privoxy's</application>
+ arsenal, only a few are used for ad blocking. <link
+ linkend="actions">Actions</link>, and <link linkend="actions-file">action
+ configuration files</link>, are explained in depth below.
+</para>
+<para>
+ Actions are specified in <application>Privoxy's</application> configuration,
+ followed by one or more URLs to which the action should apply. URLs
+ can actually be URL type <link linkend="af-patterns">patterns</link> that use
+ wildcards so they can apply potentially to a range of similar URLs. The
+ actions, together with the URL patterns are called a section.
+</para>
+<para>
+ When you connect to a website, the full URL will either match one or more
+ of the sections as defined in <application>Privoxy's</application> configuration,
+ or not. If so, then <application>Privoxy</application> will perform the
+ respective actions. If not, then nothing special happens. Furthermore, web
+ pages may contain embedded, secondary URLs that your web browser will
+ use to load additional components of the page, as it parses the
+ original page's HTML content. An ad image for instance, is just an URL
+ embedded in the page somewhere. The image itself may be on the same server,
+ or a server somewhere else on the Internet. Complex web pages will have many
+ such embedded URLs.
+</para>
+
+<para>
+ The actions we need to know about for ad blocking are: <literal><link
+ linkend="block">block</link></literal>, <literal><link
+ linkend="handle-as-image">handle-as-image</link></literal>, and
+ <literal><link linkend="set-image-blocker">set-image-blocker</link></literal>:
+</para>
+
+<para>
+ <itemizedlist>
+
+ <listitem>
+ <para>
+ <literal><link linkend="block">block</link></literal> - this action stops
+ any contact between your browser and any URL patterns that match this
+ action's configuration. It can be used for blocking ads, but also anything
+ that is determined to be unwanted. By itself, it simply stops any
+ communication with the remote server and sends <application>Privoxy</application>'s
+ own built-in BLOCKED page instead to let you now what has happened.
+ </para>
+ </listitem>
+
+ <listitem>
+ <para>
+ <literal><link linkend="handle-as-image">handle-as-image</link></literal> -
+ tells <application>Privoxy</application> to treat this URL as an image.
+ <application>Privoxy</application>'s default configuration already does this
+ for all common image types (e.g. GIF), but there are many situations where this
+ is not so easy to determine. So we'll force it in these cases. This is particularly
+ important for ad blocking, since only if we know that it's an image of
+ some kind, can we replace it with an image of our choosing, instead of the
+ <application>Privoxy</application> BLOCKED page (which would only result in
+ a <quote>broken image</quote> icon). There are some limitations to this
+ though. For instance, you can't just brute-force an image substitution for
+ an entire HTML page in most situations.
+ </para>
+ </listitem>
+
+ <listitem>
+ <para>
+ <literal><link
+ linkend="set-image-blocker">set-image-blocker</link></literal> - tells
+ <application>Privoxy</application> what to display in place of an ad image that
+ has hit a block rule. For this to come into play, the URL must match a
+ <literal><link linkend="block">block</link></literal> action somewhere in the
+ configuration, <emphasis>and</emphasis>, it must also match an
+ <literal><link linkend="handle-as-image">handle-as-image</link></literal> action.
+ </para>
+ <para>
+ The configuration options on what to display instead of the ad are:
+ </para>
+ <simplelist>
+ <member>
+ <emphasis>pattern</emphasis> - a checkerboard pattern, so that an ad
+ replacement is obvious. This is the default.
+ </member>
+ </simplelist>
+ <simplelist>

+ (shortcut: <ulink url="http://p.p/">http://p.p/show-status</ulink>). This
+ is an internal page, and does not require Internet access. Select the
+ appropriate <quote>actions</quote> file, and click
+ <quote><guibutton>Edit</guibutton></quote>. It is best to put personal or
+ local preferences in <filename>user.action</filename> since this is not
+ meant to be overwritten during upgrades, and will over-ride the settings in

- Multiple actions files may be defined in <filename>config</filename>. These

- Again, the main configuration file is named <filename>config</filename> on

- Assigns the value <literal>/etc/privoxy</literal> to the option
- <literal>confdir</literal> and thus indicates that the configuration
- directory is named <quote>/etc/privoxy/</quote>.

- like the <quote><link linkend="aliases">alias</link></quote> sections which will be discussed later. For now
- let's concentrate on regular sections: They have a heading line (often split
- up to multiple lines for readability) which consist of a list of actions,
- separated by whitespace and enclosed in curly braces. Below that, there
- is a list of URL patterns, each on a separate line.

</para>
<para>
applicable actions for the URL is incrementally updated, using the heading
of the section in which the pattern is located. If multiple matches for
the same URL set the same action differently, the last match wins. If not,
- the effects are aggregated (e.g. a URL might match both the
- <ulink url="actions-file.html#HANDLE-AS-IMAGE"><quote>+handle-as-image</quote></ulink>
- and <ulink url="actions-file.html#BLOCK"><quote>+block</quote></ulink> actions).
-
