Q:

Redirect without change URL

is it possible to redirect an URL www.siteA.com to www.site2.com/Default.aspx?SiteSource=siteA without changing the browser's URL?
Similarly, accessing www.siteA.com/Page2.aspx will redirect to the www.site2.com/Page2.aspx?SiteSource=siteA

A:

You can also use mod_proxy (or similar functionality for a different web server) so that the page your server serves is the same as the remote page. But this has some security and performance implications (you're letting the client make your server do arbitrary work copying data across the network from the remote server).
