- ad banners). If you want them to be treated as if they were images, so
- that they can be invisible, then move the offending URL from the
- "+block" section to the "+imageblock" section of your actions file.

3.2. Configuration Files Overview
For Unix, *BSD and Linux, all configuration files are located in
- /etc/junkbuster/ by default. For MS Windows, OS/2, and AmigaOS these

The installed defaults provide a reasonable starting point, though
possibly aggressive by some standards. For the time being, there are

as well with differing levels of filtering and blocking, e.g.
ijb-basic.action.)
- * The re_filterfile file can be used to re-write the raw page
+ * The default.filter file can be used to re-write the raw page
content, including viewable text as well as embedded HTML and
JavaScript, and whatever else lurks on any given web page.
- ijb.action and re_filterfile can use Perl style regular expressions
- for maximum flexibility. All files use the "#" character to denote a
- comment. Such lines are not processed by Junkbuster. After making any

you can make it a comment and it will be treated as if it weren't
there. This is called "commenting out" an option and can be useful to

modification can be removal, or re-writing, of any web page content,
including tags and non-visible content. The default filter file is

The included example file is divided into sections. Each section
begins with the FILTER keyword, followed by the identifier for that

- applied, change these rules and other configuration options, and even

8.3. Anatomy of an Action
- The way Junkbuster applies "actions" 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 see just what Junkbuster is doing. Especially,
- if something Junkbuster 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 "regular
- expressions" whose consequences are not always so obvious.
-
- First, you enter one URL (or partial URL), and this page will tell you
- how the currently configured Junkbuster "actions" are being applied to
- that specific URL. This will not help with filtering effects from the
- re_filterfile! 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 "View Page Source" option for this.
-
- Let's look at an example, [81]google.com, one section at a time:
+ The way Privoxy applies "actions" to any given URL can be complex, and

+ need to be able to see just what Privoxy is doing. Especially, if
+ something Privoxy 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 "regular expressions" whose
+ consequences are not always so obvious. Privoxy provides the
+ [81]http://ijbswa.sourceforge.net/config/show-url-info page that can
+ show us very specifically how actions are being applied to any given
+ URL. This is a big help for troubleshooting.
+
+ First, enter one URL (or partial URL) at the prompt, and then Privoxy
+ will tell us how current configuration will handle it. This will not
+ help with filtering effects from the default.filter! It also will not
+ tell you about any other URLs that may be embedded within the URL you

+ Page Source" option for this.
+
+ Let's look at an example, [82]google.com, one section at a time:

- defaults. This is basically what Junkbuster would do if there were not
+ defaults. This is basically what Privoxy would do if there were not
any "actions" defined, i.e. it does nothing. Every action is disabled.
This is not particularly informative for our purposes here. OK, next
section:
file, and "google.com" is referenced in these sections.
And now we pull it altogether in the bottom section and summarize how
- Junkbuster is appying all its "actions" to "google.com":
+ Privoxy is appying all its "actions" to "google.com":
