Despite having H2 enabled in Undertow https connector, Apache HTTP Server with mod_proxy-cluster terminates H2, i.e.
- client <--> httpd communication is H2
- direct client <--> worker is H2
- but when client is served by worker via httpd, HTTP 1.1 is used between httpd and workers: client <-
H2> httpd <HTTP 1.1-> worker - from the client's point of view, H2 is used, but in fact, it is used just between client and balacer, not all the way to the worker
From Wildfly Undertow access log:
Accessed through httpd balacner:
192.168.122.172 - "GET /clusterbench/requestinfo HTTP/1.1" 200 1399 192.168.122.172 - "GET /clusterbench/requestinfo HTTP/1.1" 200 1399 192.168.122.172 - "GET /clusterbench/requestinfo HTTP/1.1" 200 1399 192.168.122.172 - "GET /clusterbench/requestinfo HTTP/1.1" 200 1399
Balancer is checking worker's availablity:
