HTTPS to HTTPS on HTTP to HTTPS redirect iRule

I would probably split the configuration into two irules. If you apply this one on your 443 VS you'll likely experience and endless redirect loop as your first if statement will be hit everytime and give you a redirect leading you to hit it again.

On your 80 VS you can apply the _sys_https_redir On your 443 VS you can use ([HTTP::host] equals "webappsdev") as your if condition

It should not be necessary to explicitly state the forward part.
