A Rewrite engine is a piece of computer software used to modify URLs for a variety of purposes.

Apache HTTP server has a rewrite engine called mod_rewrite.

There are also rewrite engines for other web servers such as Microsoft's Internet Information Server (IIS).

A detailed description of Apache's mod_rewrite is available on the Apache.org website.
