I load balance two Apache Tomcat instances (5.5.27 - jdk 1.5.0_22) with mod_proxy. Intermittently the Content-Type header of the response does not relate to the actual content type. Instead we receive "text/plain".
When connecting directly to the Tomcat http port, instead of going through the Apache balancer, we do not experience this problem. Server info: CentOS release 5.3 (Final) 32bits Server version: Apache/2.2.3 (httpd-2.2.3-92.el5.centos) Server built: Jul 18 2016 10:51:39 I know the version is old, but we cannot update to 2.4 because this is a production server. The proxy configuration: <Proxy balancer://clusteraeprod-scae/> BalancerMember http://aepru01:8081 route=nodo1 BalancerMember http://aepru02:8081 route=nodo2 ProxySet stickysession=JSESSIONID </Proxy> <Location /cm> ProxyPass balancer://clusteraeprod-scae/cm ProxyPassReverse http://aepru01:8081/cm ProxyPassReverse http://aepru02:8081/cm </Location> I'm unable to find any information whether this is a known bug. If not, what can we do to try to locate the problem? Thanks in advance.
