iRule causing http connection resets

I have an iRule that is set up to do redirects based on host and uri. Whenever I try to access sites on the virtual server that the iRule is attached to, I immediately get a "connection reset" error in the browser. Fiddler shows "[Fiddler] ReadResponse() failed: The server did not return a complete response for this request. Server returned 0 bytes."

I've turned on RST logging, and attached a screenshot of the relevant section of the log. aaa.aaa.aaa.aaa is the main external IP address (no virtual servers assigned to it). bbb.bbb.bbb.bbb is the external IP address of the virtual server having the issue. This is a virtual edition running in Azure. Any ideas?

    Below is not working. Any ideas ?

    when HTTP_REQUEST {

    if { [HTTP::has_responded] } { return }

      switch -glob [string tolower [HTTP::host]] {

        "abc,company.org" {

          if { [HTTP::has_responded] } { return }

           HTTP::redirect "https://abc,company.org/sites/policies"

              return

         }

        }

       }
