	Using an URL rewrite engine, the website software can be presented with URLs in one form, while actual requests (and URLs seen by the user) are in another form. So rewrite engines allow URLs to be tidied up and made more user friendly, by configuring rewrite rules, rather than modifying the webserver software.

+A '''rewrite engine''' is a piece of [[LAMP|web server]] software used to modify URLs, for a variety of purposes. Some benefits derived from a rewrite engine are:
 * Making website URLs more user friendly
 * Making website URLs more search-engine friendly
-* Preventing undesired "[[inline linking]]"

 * Not exposing the (web address related) inner workings of a website to users
-Many of these only apply to HTTP servers whose default behaviour is to map URLs to [[filesystem]] entities (i.e. files and directories); certain environments, such as many HTTP [[application server]] platforms, make this irrelevant.
