           Summary: Konqueror does not respect HTTP header cache-control
           Product: konqueror
           Version: 4.6.0
          Platform: Compiled Sources
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: NOR
         Component: general
        AssignedTo: konq-bugs@kde.org
        ReportedBy: sebastien.renard@digitalfox.homeip.net


Version:           4.6.0 (using KDE 4.6.1) 
OS:                Linux

Hello,

When a webserver server answer with the following HTTP header : 
Cache-Control    no-cache, no-store, must-revalidate

The browser should not keep the page in cache at all, and, for example, when
going to another page and hitting the "back" button, it must reload the page.
That's very usefull to force reload of an html form to avoid data
inconsistence.

Firefox does respect those headers and reload properly the page in such a case.
Konqueror does not.

Reproducible: Always

Steps to Reproduce:
1/ Open a web page that anwser with Cache-Control    no-cache, no-store,
must-revalidate

2/ go to another page

3/ hit the back button


Actual Results:  
The page is taken from cache

Expected Results:  
It should had been reloaded from server to respect cache-control-policy
