Description mike.zraly 2010-11-23 10:19:27 PST 
The QWebSettings::setOfflineWebApplicationCacheQuota() method deletes all records from the application cache database before it sets the cache quota.  This is unexpected and undocumented.  It is not possible to change -- even INCREASE -- the quota without discarding all the old application cache data.

Note: there is already a bug filed to add an API for managing quotas in the app cache:

Please follow this to report bugs on QtWebKit: http://trac.webkit.org/wiki/QtWebKitBugs

Would you mind attaching a test case?

This seems to be done intentionally to match the behavior of other platforms (mac & gtk).

The behavior is intentional.
