[Download RAW message or body]
Hi
We have Apache 2.4.38 and two Wildfly 10.1 servers.
Apache is configured as a reverse proxy for each Wildfly server as follows.
in ssl.conf
ProxyPassReverse /loga/ http://127.0.0.1:8180/loga/
ProxyPassReverse /loga3/ http://127.0.0.1:8080/loga3/
Apache and the Wildfly servers are enabled for http2.
At a customer site we observed that when Apache was under load it was routi=
ng requests to the incorrect Wildfly,
e.g. a request for the loga server went to the loga3 server or vice versa.
We were not able to reproduce this in the lab. For the customer the workaro=
und was to disable http2 for both Wildflys.
Is this a known problem with Apache?
We are currently testing Apache 2.4.46, but as I said we were unable to rep=
roduce the customer problem so we are reluctant to reactivate http2.
I would be grateful for any suggestions as to how to locate/solve this prob=
lem.
Regards and Thanks
Richard Hennessy
