A rewrite engine is a piece of web server software used to modify URLs before fetching the requested item, for a variety of purposes. This technique is known as URL rewriting. Some benefits derived from a rewrite engine are:
* Making website URLs more user and search engine friendly
* Preventing undesired “inline linking” or “hot linking”
* Not exposing the (web address-related) inner workings of a website to users
