Well I have a weired issue, I was trying fronting tomcat with apache mod_jk using worker.
If I update my form with something like http://server.internal:8080 i.e tomcat then it works fine i.e updates are shown on screen and onrefresh the updates retain.
But if I update form with apache i.e http://server.internal/ then updates are seen in database but on refresh UI shows old values only, after refreshing 5-10 times then UI shows new values.
Also during refresh sometimes it shows old values while sometimes new values in the form.
I am using tomcat 7 + apache 2.2 + mod_jk on windows server.
I have disabled caching modules but still getting error.
Not sure where and how to debug such an issue.

Does not look a caching issue, tried with KeepAlive off also
I think its problem with the browser local history, delete the history in your browser and try again.mostly it will works fine.
