It should be the second actions file loaded and shouldn't be edited by the user.

are processed in the order they are defined. Local customizations and locally
preferred exceptions to the default policies as defined in

where you can preserve them across upgrades. The file isn't installed by all

lurks on any given web page. The filtering jobs are only pre-defined here;
whether to apply them or not is up to the actions files.
<TT

available for use by the developers. Some are much more intrusive than
others, and all should be used with caution. You may define additional
filter files in <TT

locally defined filters or customizations.

Privoxy versions, unfortunately some enhancements cost backwards compatibility.
</P

> All files use the <SPAN
CLASS="QUOTE"
>"<TT
CLASS="LITERAL"
>#</TT
>"</SPAN

comment (the rest of the line will be ignored) and understand line continuation
through placing a backslash ("<TT
CLASS="LITERAL"
>\</TT
>") as the very last character
in a line. If the <TT
CLASS="LITERAL"
>#</TT
> is preceded by a backslash, it looses
its special function. Placing a <TT
CLASS="LITERAL"
>#</TT
> in front of an otherwise
valid configuration line to prevent it from being interpreted is called "commenting
out" that line. Blank lines are ignored.</P
><P
> The actions files and filter files
can use Perl style <A

maximum flexibility.</P
