Using username as subdomain

[eluser]achilez[/eluser]
I plan to create a new social networking site like multiply, stumbleupon, facebook, friendster and more. but i need your help me to figure out on how to use a username as subdomain in codeigniter.

i.e.
http://myusername1.mydomain.com
http://myusername2.mydomain.com
http://myusername3.mydomain.com
and more...

Any help would appreciate it so i can proceed on my project.

Thanks!

More than likely you are just going to be doing mod_rewrite to change say /user/john to john.mydomain.com. I am not familiar with the mod_rewrite commands to achieve this but I'm sure a quick search wil net you what you are looking for.

can someone help me figure out the correct command for mod_rewrite on .htaccess? or do you have any other solution?
