Mod_rewrite. Available Languages: en | fr Summary The mod_rewrite module uses a rule-based rewriting engine, based on a PCRE regular-expression parser, to rewrite requested URLs on the fly.


By default, mod_rewrite maps a URL to a filesystem path. However, it can also be used to redirect one URL to another URL, or to invoke an internal proxy fetch. mod_rewrite provides a flexible and powerful way to manipulate URLs using an unlimited number of rules. Mod_rewrite operates on the full URL path, including the path-info section.
