Description:

The mod_rewrite module uses a rule-based rewriting engine, based on a
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. Each rule can have an unlimited number of
attached rule conditions, to allow you to rewrite URL based on server
variables, environment variables, HTTP headers, or time stamps.

mod_rewrite operates on the full URL path, including the path-info section. A
rewrite rule can be invoked in httpd.conf or in .htaccess. The path generated
by a rewrite rule can include a query string, or can lead to internal
sub-processing, external request redirection, or internal proxy throughput.

Further details, discussion, and examples, are provided in the detailed
mod_rewrite documentation.
