Hey Chris,

 

you really need an HTTP VS to terminate the TCP:80 connection and send a HTTP redirect back to the client.

 

Without having a TCP:80 VS you may use "Preloaded HSTS" to redirect the HTTP requests already within the browser, even before the very first TCP:80 connection is send. But this would still have some serious restriction/limitation...

 

So once you have created an additional TCP:80 VS (HTTP Profile must be applied without any Pools selected) you could use the build in iRule "_sys_https_redirect", which simply redirects every HTTP request to HTTPS using the same hostname and URI.

 

BTW: I would recommend to either use the LTM admin page or the iRule Editor to create or change iRules.

 

Cheers, Kai
