+The SetFilter directive maps a filter stack to the specified content
+type.
+</P>
+<P>
+Example: <BLOCKQUOTE><CODE>
+SetFilter server-parsed INCLUDES CACHE
+</CODE></BLOCKQUOTE>
+</P>
+<P>
+Then any document with the server-parsed MIME-type will pass through the
+INCLUDES and CACHE filters. The filters are added in the same order that
+they are specified in the config file.
+</P>
+<P>
+This can be very powerful when combined with either the <A HREF="#addtype">
+AddType</A> or <A HREF="#addhandler">AddHandler</A> directives. This allows
+you to specify an extension for a MIME-type and a set of filters for files
+with those extensions to be passed through
+</P>
+<PRE>
+AddHandler server-parsed .shtml
+SetFilter server-parsed INCLUDES
+</PRE>
+<P>
+documents with the extension "<CODE>.shtml</CODE>" would be passed through
+the INCLUDES filter.
