now i am developing a online shopping website using CI 1.7.1 . Here each member can create their own website, member related codes are put in a subfolder called qbiz. And developed a page in the root folder to list all members. when i click any of the member from root folder his home page will open in qbiz.

At that time the url is like this

http://www.mmcq.in/gulfq/qbiz/Bigil/14

I want to change this url to Bigil.mmcq.in and it must run the index function of home page in qbiz.
