Enable WebSocket support on nginx for infrastructure gateway
100%
Description
WebSocket is a protocol providing full-duplex communication channels over a single TCP connection. It basically allows full-duplex communication between clients and server.
Although tomcat 7 supports them, nginx (the reverse proxy) need some further configuration for support ws:// and wss:// (SSL Websocket)

RIght now the situation is the following:
- haproxy already transparently manages the websocket connections
- nginx needs a couple of options that are
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection "upgrade";
Those options cannot be globally set, so we need to find a way to not rewrite the nginx virtualhost every time an app activates the websockets.

I've possibly found a generic solution. Now running on dev2.d4science.org.
The details:
map $http_upgrade $connection_upgrade {
default upgrade;
'' close;
}
sets the variable if the client sent the header, empty otherwise. Then, in the virtualhost reverse proxy configuration:
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection $connection_upgrade;

so far so good, but I'll wait some days and more testing to close the task
