HTTP Redirect OWA without SSL

Where I work we try to write what we call "any.any" iRules. Meaning that we can apply it to any Virtual Server and get the same result.

This is our HTTPS to HTTP Redirect iRule. It will get the [HTTP::host] and [HTTP::uri] of whatever you apply it to and redirect it to HTTP.

when HTTP_REQUEST {
  HTTP::redirect http://[getfield [HTTP::host] ":" 1][HTTP::uri]
}

The key is where you apply the iRule. Do NOT apply an HTTPS to HTTP Redirect to your HTTP Virtual Server (only your HTTPS Virtual Server) or you will create an endless loop.
