From: Joshua Slive A filter is a process which is applied to data that is
sent or received by the server. Data sent by clients to the server
is processed by input filters while data sent by the
server to the client is processed by output filters.
Multiple filters can be applied to the data, and the order
-of the filters can be explicitly specified. In addition,
-since filters apply to all content, they allow for flexible
-manipulation of data such as processing the output of
-CGI scripts for Server Side Includes.
The set of filters which apply to data can be manipulated +
Filters are used internally by Apache to perform functions such as
+chunking and byte-range request handling. In addition, modules can
+provide filters which are selectable using run-time configuration
+directives. The set of filters which apply to data can be manipulated
with the SetInputFilter
and SetOutputFilter
directives.
The only filter currently included with the Apache distribution
-is the INCLUDE
filter which is provided by
-mod_include to process output
-for Server Side Includes. There is also an experimental module
-called mod_ext_filter
-which allows for external programs to be defined as filters.
The only configurable filter currently included with the Apache
+distribution is the INCLUDES
filter which is provided by
+mod_include to process output for
+Server Side Includes. There is also an experimental module called mod_ext_filter which allows for
+external programs to be defined as filters.
