Hello,

I've just fixed on GIT the issue where the tcp_persistent_flag was ignored for websocket TCP connections ( as of commit 320c825 ) - please update your sources and the issue should be fixed, without having to change the tcp_connection_lifetime.

Best Regards,

Hello,

More tests with WebRTC in Opensips 2.1 and I noticed that the websocket connection of my browser was being disconnected some time after it registered, this caused the javascript lib to reconnect and re-register. This is not good because each time it happens, the browser uses a new port and I get one more contact to the same AOR in my location table... Investigating the problem I noticed the websocket connection was being dropped because the Opensips' TCP connection lifetime was being reached and so it closed the connection. First thing I did was to use the tcp_persistent_flag from the Registrar module. Unfortunately it didn't work.... So next test was to increased the tcp_connection_lifetime parameter to something greater than the Register expire time and luckly it worked! The websocket connection wasn't dropped anymore!
Even though now things are working, I think we have some bug in here...
I know the websocket runs over TCP but should it be ruled by the tcp_connection_lifetime parameter? I was expecting some independence, although I would completely understand if it is not possible from the implementation point of view. Despite that, considering websockets fall under the same rules as TCP, then the tcp_persistent_flag should apply for it too, right?

Regards,
Patrick
