Dear Ruslany, There is an issue in the URL (HyperLink, Response.Rewrite(), and LinkButton links).. http://subdomain1.mysite.com /default.aspx is internally rewritten to http://subdomain1.mysite.com /subdomain1/default.aspx Now the links are created are : http://subdomain1.mysite.com /subdomain1/newpage...

Dear Ruslany, I have done the same thing and its now working. But there is a little issue. It also rewrite for www. Like: http://www.mysite.com to http://mysite.com /www/ That mean I am not able to access my main site content. This rule should work for all the subdomain but not for www. Regards, Sandeep

How about the reverse of this? How can I point: www.domain.com/subdomainname to subdomain.domain.com and making sure that any subsequent pages after the /subdomainname also maps correctly such as: www.domain.com/subdomainname/page1.aspx would map to subdomain.domain.com/page1.aspx Any help would be appreciated...
