A rewrite engine also known as URL rewriting, is software which modifies the URLs appearance, for example:

http://example.com/wiki/index.php?title=Page_title

is changed to:

http://example.com/Page_title

The benefits of a rewrite engine are^[1]:

Making website URLs more user and search engine friendly
Preventing undesired "inline linking"
Not exposing the inner workings of a web site's address to visitors

[edit] Java and Ruby on Rails

In Java, the term "URL rewriting" sometimes describes a Web Application Server adding a session id to a URL when cookies are not supported (e.g. "index.jsp" is rewritten to "index.jsp;jsessionid=xyc" when the links are drawn in an HTML page).

Ruby on Rails has built-in URL rewriting via Routes.^[2]

[edit] Notes

^ Many of these only apply to HTTP servers whose default behavior is to map URLs to filesystem entities (i.e. files and directories); certain environments, such as many HTTP application server platforms, make this irrelevant.
