websocket support for WAF
we are hosting a SignalR hub (http://signalr.net/) behind a Sophos UTM 320. We use the Web Server Protection feature extensively in our environment, and as such have opted to use the same for this.
SignalR will always try to use Web Sockets (http://en.wikipedia.org/wiki/WebSocket), a new HTML5 API, and fallback to other technologies where this isn't possible to be used.
Since we've been hosting the hub via the reverse proxy, none of our clients are able to connect via Web Sockets :so having support for websockets in WAF would be super cool
This should be easy to do for Sophos as there is now a mod_proxy_wstunnel that provides this. Sophos just need to bump the version of apache they use to 2.4.5 or later (better to use 2.4.9) and allow for it in the configuration.
