[TYPO3] Specifying page name in place of id in url

[Sumit Malik]

Hi all,
 
 I want to specify page names instead of id in the typo3 url.
 
For example:
 
In place of 
http://mylocalhost/mysite/index.php?id=30
 
the following url should work
 
http://mylocalhost/mysite/mypage.php
 
 
How can I achieve this?
 
 
Thanks,

Sumit Malik
