Cross domain redirect on login

Hi,

I think cross domain redirects were stopped on an earlier version of WordPress, obviously becuase of the security risk.

However, I’d like to be able to do that on my site… I have a login form running on all my pages and would like the user to be redirected to my community section when they login on certain pages.

The community section is on a subdomain.

Is there anyway I can allow a cross-domain redirect to one of my subdomains??

Thanks,
Oli
