if you're trying to save yourself a lookup, you can't do a redirect there but you should be able to stash a result into the request (maybe a header?) for the redirect, and then catch it at a later point.
if you're trying to do a clean redirect, it won't work. if edf.com does not have a valid cert, you need to set a backup certificate for the redirect but the client may reject that redirect -- it will be sent on an invalid cert that doesn't match the request (the cert's domain, date or other data will not be valid for the request)
