Topic: Request not showing in apache access log but shows in Tomcat

[shantanujoshi]

RHEL version 7
Apache version: 2.4.27
Tomcat version: 8.5.16
Siteminder version: 12.52.105.2112
Application uses websockets.
Application uses Angular on the client side.

Request from browser are intercepted by Siteminder to authenticate the user. There after request is forwarded to Tomcat. When the application is launched initially, everything works fine.

Application has logic to prompt the user if application is unused for a certain period of time. After that time expires, application shows a message on the browser to relaunch the application. Relaunch of the application causes it to go through the same sequence of requests as if an application is launched afresh. At the time of relaunch some of the requests don't seem to show in apache access logs but they do show in Tomcat localhost access logs.

What might be causing this ?

Note: The issue only happens with RHEL 7. With RHEL 6 we do not see this behavior.

Here is how we connect httpd to Tomcat

ProxyPass /login !
ProxyPass /myapp/websocket/events ws://localhost:12710/myapp/websocket/events
ProxyPass / http://localhost:12710/

Please post the part of the config how you connect httpd with tomcat.
