Apache :: CSRF between Apache and Tomcat

hdevine

We have a project that operates on Tomcat via port 8080. We need to have the content protected by Apache via SSL, which we have working with a certificate we purchased. We then set up an Apache virtual host listening on 443 to ProxyPass the desired application to http://localhost:8080/app.

When we go right to the application via Tomcat, everything works. In other words, http://localhost:8080/app loads fine. However, if we try https://localhost/app, we see a bunch of errors in the browser's debug console stating that CSRF_GUARD_JS cannot be found. We have been working with both the vendor of the software (who suggested we look on this site), as well as Red Hat, as our server is RHEL 7.5.

The vendor is telling us that they believe that Tomcat is sending out a security token, and Apache is not responding to it accordingly, and therefore, causing our issue. Red Hat has been looking at it for several days, and they can't find what needs to be done in a cookie or request header to allow this to work.

Does anyone have any ideas? We have been dealing with this issue for several weeks, and our users refuse to use the software without this being corrected. I just can't seem to get any answers from anyone at this point.

I can provide Apache and/or Tomcat logs in the morning, as I'm not at the office right now.

Thanks,

You might can avoid that if you connect to Tomcat with ajp instead of http.

If I do that, I get "503 Service Unavailable The server is temporarily unable to service your request due to maintenance downtime or capacity problems. Please try again later.". I changed this in my .conf file for the virtual host under /etc/httpd/conf.d. Do I need to change anything in the Tomcat configs too?

Thanks,

Is ajp enabled in tomcat's server.conf?
