Hi
Which version of WinGate is this?
We find there are many pages on servers which are not HTTP compliant. Some browsers are very forgiving of these sorts of problems. That log message indicates that the server didn't properly frame up the response message.
Do you have the URL of this site we can test with? Post it to our support desk (email to
support@wingate.com) if you don't want to publish it here.
Regards
Adrien
