iRule forward URL to different domain for http and https

If blah.domain2.com and another hostname like domain1.com or www.domain1.com are resolving to the same VIP, then clients will get a mismatched cert warning on HTTPS requests when trying to access a hostname that the cert isn't issued for. You would want to have a cert installed which matches the hostname(s) that the client is making the request to--not the domain that you're redirecting the clients to.

 

 

You could either get a single cert which is valid for all the domains (using subject alternate names and/or a wildcard cert) or change the name resolution to point to separate IP addresses.
