LTM check http or https the request and make action to it

Create a virtual server that listens on the specified IP address, Port 80, and attach that irule to it. Add a redirect for the HTTPS version in an else clause.

Pseudocode example:

 if (uri_matches) {
    redirect to port 443
 } else {
    accept request (do nothing)
 }

You can also use a condition that checks for "TCP::local_port clientside" and reject if you get 80 (or whatever port your non-HTTP service is listening on).

Pseudocode example

if (TCP::local_port eq "80" and uri_matches) { 
   redirect
}

I'm not aware of a way to ask the question "is this an SSL connection"? Others can chime in if they have better ideas.
