>>but when I click on a room, the link point to http://chat.mydomain.com/chat/CH_MainForm.aspx
If you want the link point to http://mydomain.com/chat/CH_MainForm.aspx instead of http://chat.mydomain.com/chat/CH_MainForm.aspx, you can just go to this page: http://mydomain.com/chat.aspx, right click, copy the HTML source and paste it to http://chat.mydomain.com/chat.aspx page.
