I get this error when I go to a Sharepoint site through a watchguard http proxy.
Response denied by WatchGuard HTTP proxy.
Reason: header 'Content-Type' denied rule='Default' value='(none)'
Method: GET
How can I set up the proxy to allow this site through without opening up the (none) category, which kind of defeats the purpose of the proxy OR how do I modify the sharepoint site to not supply a "none" for Content-Type?

I have gone into the settings and set it to a different view (text list) and it allows me to turn on (none) and allow websites with missing content types to come through. This seems a little bit of a waste of a proxy as it opens it up to letting anything that is not coded correctly through but I don't see any other way.

There is a simple thing we can do to solve the problem, we can create a filteredHTTP service and allow outbound traffic from specific host or entire subnet to sharepoint website only. To do this we configure the service as below:
FilteredHTTP
Incoming "Disabled"
Outgoing "Enabled and Allowed"; from specific-host-ip OR subnet-ip; to public-ip-of-sharepoint-we
This way only the sharepoint traffic goes through filtered-HTTP service and rest all traffic continues to go through the proxied-HTTP service.
One other thing which you can try doing is (if you not wish to add another service) is to uncheck "block unknown content-type" and "unknown header" checkboxes and see if that solves the problem (not sure if this would solve problem 100%, as there might be something more than just header and content-type.
Please let me know if you need more details.
Thank you.
