Rewrite engine

A rewrite engine is a piece of web server software used to modify URLs, for a variety of purposes. Some benefits derived from a rewrite engine are:

Making complex web site structures search-engine friendly

Preventing undesired hot linking

Not exposing the (web address related) inner workings of a website to users

The Apache HTTP server has a rewrite engine called mod_rewrite, which has been described as the Swiss Army knife of URL manipulation .
