Content Filtering in Apache

The strength of the Apache Filter chain is the ability to process a data stream independently of the generation of the stream, so we can apply identical processing to, for example, a static file, a CGI script, or a proxy handler.

Some examples of content filter modules for Apache include

  • mod_include, Apache's implementation of Server Side Includes.
  • mod_transform transforms XML markup using an XSLT stylesheet.
  • mod_proxy_html rewrites HTML links into a proxy's address space
  • mod_charset_lite changes the character encoding of text files served.
  • mod_deflate compresses or uncompresses files according to browser preferences.
