Infinite loops on server side
Well...
I got this thing called Pychat, with a server and a client, and I have this idea. I want to add a feature that detects when someone closes their tab, so I can say that they left. I already tried using threading, but it froze the server.
Server Unrelated note: Can someone try hacking the server?
This gives me much trouble.

@mwilki7 It's not python, so I can't use it.

@ebest Use JavaScript to send some sort of HTTP response to the python server and have the server handle the response from there.

@mwilki7 It's not even a tab, so I can't really monitor it. Also, I don't know https, javascript, or css.
I didn't review the code, but why not have the client send a heartbeat every 10 seconds? Basically, they just send a tiny packet to the server at regular intervals to say "Hey, I'm still here!". If the packet isn't received on time, then you can assume they left / got disconnected and take it from there.
@samdevz I've actually already done that. It already checks in a while True loop for messages, so I added an extension to that. It only works if someone's on, though.
