Redirect all HTTP traffic to HTTPS://domain/owa

Welcome to the forums.

First of all, it's imperative to use the right "event" for your iRule. In this case, you want to use HTTP_REQUEST. HTTP_RESPONSE happens once the F5 LTM receives a response from your pool members.

Give this a shot. It'll send whatever the user requests to the same URL but over HTTPS. If instead you'd like to change the hostname or URI, simply change it below. üòâ

when HTTP_REQUEST {
   HTTP::redirect "https://[HTTP::host][HTTP::uri]" }
