whats that site about? kinda products?

use java script to do this as dynamic but consider that if java is disabled it will not work... or refresh meta content

ask the provider the full path of your website and replace it present one.

thank you for the idea...

my friend asked about masking real addresses shown in address bar...
normally:
http://www.myhost.com/index.asp?username=someone

he wants it like:
http://username.myhost.com

how can we do...

at the end of the pages add a privated page ID and post it with other datas. then add if else circle...

add a new coloumn (e.g: level ) in your table and set management levels for users like :

1 => Administratros
2 => Users

then create your sql query which includes only
userid and level...
