OnlineOptions ignored

Hi wwwoffle-users,

I have tried to achieve that cached pages are requested only if the cached 
version is older than specified (500 minutes) and fetched only if they have 
changed. A few specific pages are not to be re-requested at all. I have set 
the OnlineOptions accordingly (so I thought).

What happened was:
- pages are re-fetched from the server though the cached version is newer than 
specified, even twice (or more) per session.
- unchanged pages are downloaded again (and again and again).

Apparently the settings in this section are completely ignored. I have not 
been able to figure out what went wrong. Has anyone encountered a similar 
problem (and found a solution to it)? Could this problem be browser-related? 
I am using wwwoffle 2.8a and konqueror.

TIA and Best Regards

Andreas
