how to keep websocket connect until either-side close?

Question

I'd like to build chat app on websocket, and choose Poco C++ lib as webserver (1.4.6p1). There are multiple user at the same time, poco websocket will be blocked at read frame but automatically released after 60 seconds if nothing is received from browser.

I want to keep socket connected in order to manager so many active (or idle) users, but how to get there?

yes, I have resolved by myself. – Paulus

it would be interesting, HOW ;-) – Proto

easy, on server side, process PING and PONG message to make the connection alive before timeout, good luck – Paulus

Answer 1

I "fixed" the problem with this simple and somewhat dirty line of code:

ws.setReceiveTimeout(Poco::Timespan(10, 0, 0, 0, 0));

Basically, i set the receive timeout to 10 days. Since my websocket will have a lifespan of a few hours, 10 days equals infinity for me.

Hope it helps.

ws.setReceiveTimeout(Poco::Timespan()); sets it to true infinity – Hem

Check out this:

Poco::Net Server & Client TCP Connection Event Handler

You have some examples about how wait incomming connections, timeouts, etc.

Good luck
