I’m using the redirect\_to method with a :host parameter to change  
subdomains in a few places in my app, in one place it redirects to the  
url with the correct subdomain perfectly but in the current instance  
rails spits out:

You are being redirected.

and firebug catches the error:

uncaught exception: Security Error: Content at {url} may not load data  
from {url with different subdomain}.

I haven’t been able to find much information about this. Why would  
redirect\_to( :host =\> etc…) work in some areas but not here? Would it  
have something to do with a user being ‘logged in’? What direction  
should I go to investigate a solution this problem?

Thanks
