Non-blocking sockets not working on Nitrous.io

Question

sock = socket.socket()
sock.connect_ex(ip, 80)
sock.settimeout(30)
sock.setblocking(0)
sock.sendall(str.encode(
    "GET " + randstr + target.path + " HTTP/1.1\r\nHost: " + target.netloc + "\r\n" + str(
        cur_header) + "\r\n\r\n\r\n"))
data = sock.recv(1024)
print(data)

It seems, it works like blocking socket, because it returns data. Does Nitrous.io support non-blocking sockets?

Answer 1

Yes. Nitrous.io doesn't support non-blocking. It only support ports 1024 - 9999 now.

But you can running an app on port 3000 to forward port 80, if you are behind the firewall.
