Want to know regarding url redirection Options

[Sujit Philip]

I want to redirect "www.subdomain.mydomain.com" to http://www.somedomain.com/somefile.html

But my host doesnt allow me to have two level subdomain, i.e. "www.subdomain.mydomain.com" It only allows me to have "subdomain.mydomain.com"

Is there any way that i can add some script or some other kind of thing and make the www.subdomain.mydomain. com to redirect to a specific url?

The problem is tht i have created mail.mydomain.com to redirect to mydomain.com/mail.html. But i also want tht if somebody types www.mail.mydomain.com then he should be redirected to the same page. But tht is not working.

Is there any solution?
