configuration to the output filter chain. It enables filters to be conditionally inserted, based on any Request or Response header or environment variable, and dispenses with the more problematic dependencies built with support for files larger than 2GB on modern 32- bit Unix systems. Support for handling >2GB request bodies has also been added. Event MPM The event MPM uses a separate thread to handle Keep parsed by Apache, including their file name and line number. The module also shows the order of all request hooks and additional build information, similar to httpd -V. mod_ssl Added a support for RFC 2817
