Automatic disconnection in WebSocket

Recently, in the company to develop a use websocket for the front-end push message function, found a problem: every time if the data is not transmitted, and the previous section of the connection will automatically disconnect;

At first, the reason for the session is that the default time for the Web session is 30 minutes, but the log finds that the disconnect time interval is much less than 30 minutes; careful analysis found that the non-operating interval is exactly 90 seconds

It will be automatically disconnected; The original is our use of Nginx Proxy, nginx configured the access time-out of 90s;

Proxy_read_timeout 90;

Change the time you want;

At the same time can also be added on the front page of the heartbeat mechanism to keep the connection, here do not repeat;
