I have one domain ("domain1") that is set up with hosting and mail (hosted by Gmail Apps). This domain works perfectly.

I want a second domain ("domain2") to forward to domain1, but I don't want to use "DNS Forwarding." I would like to have it act EXACTLY like domain1, so that domain2/whatever points to the same resource as domain1/whatever WITHOUT AN HTTP REDIRECT NOR BROWSER TRICKS LIKE FRAMES. I would also love to be able to send mail to "blah@domain2" and have it go to "blah@domain1".

Can this be set up, and how? I am using GoDaddy as registrar and DNS host for both domains. GoDaddy is also the web host for domain1, and mail hosting is with Google Apps.
