Upgrade websocket at a later point

[geiseri]

I have a situation where I need to process a http request that uses a custom method (Blame Microsoft for abusing HTTP for RPC) I can handle with TemplatedApp<SSL>::any(...) to make sure a header with a cookie has specific data in it. If not I return a normal http response with unauthorized and the client can try again. If the cookie passes though it expects to upgrade to a websocket connection. I am sure I am missing something but from what I can tell TemplatedApp<SSL>::ws(...) only handles GET. Do I have to implement that same function with my custom method? Or is there an easier way?
