F5 redirects everything to root and will not let you go to Virtual Directory

Well, your redirect is stripping the query parameters off of the URL. I believe the HTTP_REQUEST event will trigger regardless of if it's using HTTP or HTTPS (at least if the BIG-IP is terminating SSL. I could be wrong here.), so you're basically always redirecting the user to the root.

Try this:

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

You'll probably want to add a condition in there that prevents the redirect if the request is already using HTTPS.
