I am uWSGI as an application server under AWS ALB and had 502 errors under load. I changed my configuration from

http-socket = 0.0.0.0:1701

to

http = 0.0.0.0:5000
http-keepalive = 1

and it seems to resolve the issue. I am not getting any 502s under the same load. I understand that uWSGI must be sending the Connection: keep-alive header in the response. However, I don’t see any such headers in the response. I also tried directing hitting 0.0.0.0:5000 from the host that runs uWSGI, but I don’t see any changes in the response. Can someone please explain how the http-keepalive option works in the uWSGI? TIA
