+<para>
+ From the webserver's perspective, there is no difference between

+ <application>Privoxy</application>. If there is a match for a <literal><ulink
+ url="../user-manual/actions-file.html#BLOCK">block</ulink></literal> pattern,
+ it will still be blocked, and of course this is obvious. Filtering is
+ potentially more of a concern since the results are not always so obvious.
+</para>
+<para>
+ <application>Privoxy</application> knows the differences in files according
+ to the <quote>Document Type</quote> as reported by the webserver. If this is
+ reported accurately (e.g. <quote>application/zip</quote> for a zip archive),
+ then <application>Privoxy</application> knows to ignore these where
+ appropriate. It is possible, however, that documents that are of an unknown
+ type (generally assumed to be <quote>text/plain</quote>) will be filtered, as
+ will those that might be incorrectly reported by the webserver. If such a
+ file is a downloaded file that is intended to be saved to disk, then any
+ content that might have been altered by filtering, will be saved too, for
+ these (probably very rare) cases.
