Load balancing: HTTPD does not support WebSockets by default
Valid from Pega Version 7.2.2
If you use a load balancer with HTTPD (Hypertext Transfer Protocol Daemon), HTTPD does not support fully functional WebSockets and sticky sessions. By default, HTTPD does not support sticky sessions, because if it did, after a session was started, the same server would serve all requests for that session.
