Will post the config when i am back home, but actually there is only one
backend so sticky sessions arent a problem, there is only one possible in
the config to go to.
Any traffic for /guacamole will go to a single server.
I think there must be something regarding how haproxy maybe waits for a
session to complete, I had hoped that the http-server-close may have helped
but it doesnt appear to.
If anyone has any other ideas let me know.
