Or is it the server instead of requests that drops the connection? So, how long does requests or rather urllib3 keep the connection alive, and is it possible to extend that time indefinitely? Or is it the server instead of requests that drops the connection? I am a beginner in python socket programming. To query the status of this socket option, call the getsockopt The main problem is that the current configuration and implementation of the TCP socket is not considering the keep-alive probe as "activity" thus, the connection is closed even if the probes If the server connection is no longer alive, calling the send method will throw an exception, so you can use a try-exception block to attempt to send data, catch the exception if it's .
