[issue41345] Remote end closed connection without response
New submission from Michal Arbet :
Hi,
I'm not sure if this is really python bug, but I hope that you can check the
issue.
Issue is that from time to time i'm getting exception from python when sending
request to server which has http keepalive option turned on.
Requests send a request but in few miliseconds apache2 server is closing
persistent connection by sending FIN packet which generate traceback.
I can reproduce it by following simple script.
#!/usr/bin/python3
import requests
from time import sleep
import logging
logging.basicConfig(level=logging.DEBUG)
s = requests.Session()
s.verify = False # self-signed cert
counter = 0
txt = "test"
while True:
counter = counter + 1
s.post('http://localhost', data={counter:txt})
sleep(5)
Everything is working fine, but from time to time I get following traceback.
When FIN is received right after request was sent.
