Http/1.1 Internal Server Error 43531 instead of StoreFront after upgrading

After upgrading to a version such as 13.0-71.44, you may see an error Http/1.1 Internal Server Error 43531 after logging into the Gateway interface instead of being redirected through to StoreFront.

This is because your session profile for Workspace/Receiver for Web contains a check for the Referer header, e.g.
REQ.HTTP.HEADER User-Agent NOTCONTAINS CitrixReceiver && REQ.HTTP.HEADER Referer EXISTS

This is documented to be correct, but does not appear to work - or at least, you may need other profiles to cover all types of client.

The quick fix is to remove && REQ.HTTP.HEADER Referer EXISTS from the session profile.
