we just migrated our web applications from tomcat5 to tomcat7. Both tomcats are running behind an apache web server. After the migration the applications are working without problems on Firefox. On I.E they are also working but after user inactivity of around 10 seconds we get the 404 error page displayed.
Configuration:
- Apache version:1.3.29 (we will also migrate this to apache 2 in few weeks)
- mod_jk version: 1.2.6
- Tomcat version: 7.0.59 (running on two different servers)
- Internet explorer version : 10
- Firefox version: 36.0
- I.E & Firefox versions are the same on every computer in our Network.
What could be the reason behind this? any advices are welcome.
Best Regards Arthur
