It should be explicitly defined in the header [1].\n\nThe problem we have here could be that the wsgi thread waiting for the message, that should execute the \"__call__\" method, does not respond, maybe due to the use of eventlet (but this is a guess and I can\u0027t prove it now).\n\nIn any case, once we move to python \u003e\u003d3.7, we can swap to streams [2], that could reduce the overload of using HTTP and webob, in favor of asyncio, an internal library.\n\n[1]https://www.geeksforgeeks.org/http-headers-connection/\n[2]https://docs.python.org/3/library/asyncio-stream.html","commit_id":"2cc35ba57a5750c244e99eb0dd750388f088ab5b"},{"author":{"_account_id":11975,"name":"Slawek Kaplonski","email":"skaplons@redhat.com","username":"slaweq"},"change_message_id":"e09a441741172a62aa3575926d87c11fb937f230","unresolved":false,"context_lines":[{"line_number":9,"context_line":"Neutron-keepalived-state-change-monitor process is using HTTP to notify"},{"line_number":10,"context_line":"L3 agent that state of the HA router was changed.
