Apache Web Forwaring

[mattbrown]

Hi
Ive been trying to find out about redirecting urls with apache but getting a bit confused

basically i have www.mydomain.com which points to the ip of my web server per normal, now some other people want to use sub omains ie something.mydomain.com etc etc so i make a new A record for something.mydomain.com which points to my apache server.

Now when somebody goes to this address i want apache to redirect them somewhere else just like somebody like 123reg would (framed). at present i overcome this by adding a virtual server for the domain then adding a php file to the virtual servers document root and getting it to send a new header but this is surely not the best way to go about this and in turn also changes the url in the users browser
