If you are writing a letter to your institute , you would probably open your word sheet and make a file named may be like lettertoinstitute.doc. The file may save in your documents directory with a full path like C:WindowsusersmaddyDocumentslettertoInstitute.doc. Single file path = Single Document.
Likewisely, If you are creating a institute website, You may create a page named page1.html, upload it and click your browser to http://www.myinstitutesite.com/page1.html. One url=One resource. Now in this case, resource is physical webpage, but it may be a either page or product drawn from a CMS.
URL rewriting changes everything. It permits you to entirly seperate the URL from the resource. By URL rewriting, you may have http://www.myinstitute.com/aboutus.html taking the user to .../page1.html or to .../about-us/ or to ../about-this-website-and-me/ or to .../youll-never-find-out-about-me-hahaha-Xy3884/. Or to all of these.Its kind of shortcuts or symbolic links on your computer hard drive. One URL=One path to search a resource.
By URL rewriting, the URL and the resource which headed could be completely independent of each other . In practicle, Usually they arn't Independent, Usually URL contains some code or numeric or name which enables the CMS to look up the resource, And in actual theory, this is what URL rewriting gives: a Complete seperation.
HOW TO REWRITE URLs:
Whether you can implement URL rewriting on a website depends on the web server. Apache usually comes with the URL rewriting module, mod_rewrite, already installed. all set-up is very common.
THE SIMPLEST CASE
The simplest case of URL rewriting is to rename a single static web page. To use Apache's URL rewriting function, you wiill need to create or edit the .htaccess file in your website's document root ( or, less commonly, in a subdirectory).
