      Description

      We are developing an application with QT 4.7.4 that is working as expected, but when making the switch to 4.8.1 we are seeing some static content not loading anymore.

      We tough that it was QTBUG-2092427 but using 4.8.2 from git our problem still occurs.

      Notes: We've only seen it on SSL and with content that it is present in the disk cache.

      With the following image, if you reload some times the bug appear

      To test it we are using the Browser app that comes with the 4.7 Demos.

      This is the console output with the network debug macros enabled:
