HTTP compression is a capability built into both web servers and web browsers, to make better use of available bandwidth. HTTP protocol data is compressed before it is sent from the server: compliant browsers will announce what methods are supported to the server before downloading the correct format; unsupported browsers will download uncompressed data. Data is usually compressed with either deflate or gzip modules specific to the server software.

  1. Lighttpd's mod_compress only supports compressing static files, that is, no content dynamically generated from a cgi/fcgi/other program. mod_deflate is a modified version of mod_compress which supports dynamic content compression but it's planned for Lighttpd 1.5.0 which is still under development.
