Unexpected CRLF with HTTP Version

If an iRule command appears to have a bug, F5 Support should open a case for you and help diagnose the issue. They won't write iRules for you though. As long as you make it clear that you think there might be a bug in an iRule command they should help.

In a quick test on 10.2.0 I didn't see a problem though:

when HTTP_REQUEST {
   if { [HTTP::version] eq "0.9"  ||  [HTTP::version] eq "" } {
      HTTP::version "1.0"
   }
}
