Redirecting subdomains to external websites

Hopefully this is a simple problem. We are attemping to use ISPConfig to combine all our different services into one Control Panel. The last piece is our DNS provider allows us to setup forwards by creating dns entries like:

webmail.domain.tld -> forwards to -> http://owa.somedomain.com

From what I have seen we should be able to mimic the same functionality by creating a subdomain under the websites and redirecting it to an external site. So I setup a subdomain and set the redirection to the site but it just keeps showing the same homepage for the main domain. I have tried the different flags and confirmed the changes are being made in the vhost.

Is there anything else I should look at or try to see why this isn't working?

Thanks

 

Use DNS

foo.example.com. CNAME bar.example.com.
bar.example.com. A 192.0.2.23

When an A record lookup for foo.example.com is done, the resolver will see a CNAME record and restart the checking at bar.example.com and will then return 192.0.2.23.

Good luck,

or you could do a http redirect from the actual subdomain....

 

Thats what he is attempting to do but failing...

 

make an index.php and add this to it:

Code:

<?php
/* This will give an error. Note the output
 * above, which is before the header() call */
header('Location: http://www.example.com/');
?>
