Under http://config.privoxy.org/user-manual/actions-file.html#FILTER there is a "Notes" section which says, in part:
Inappropriate MIME types, such as zipped files, are not filtered at all. ...
Compressed content can't be filtered either, unless Privoxy is compiled with zlib support (requires at least Privoxy 3.0.7), in which case Privoxy will decompress the content before filtering it.
At first glance, this seems self-contradictory (compressed content is never filtered, but sometimes it is filtered). Can it be clarified in the HTML file for the sake of readers who are not quite technically adept enough to understand this apparent contradiction themselves? Thanks in advance.
