URL rewriting
URL rewriting is the process of intercepting an incoming Web request and redirecting the request to a different resource. When performing URL rewriting, typically the URL being requested is checked and, based on its value, the request is redirected to a different URL. For example, in the case where a website restructuring caused all of the Web pages in the /people/ directory to be moved to a /info/employees/ directory, you would want to use URL rewriting to check if a Web request was intended for a file in the /people/ directory. If the request was for a file in the /people/ directory, you'd want to automatically redirect the request to the same file, but in the /info/employees/ directory instead.
