Hey, I just stated my opinion. No insult meant.

So what is it? I understood that you want to make html pages available offline 
so that they can be rendered later on without an internet connection.

The easiest way to accomplish this is - imho - to change the default caching 
policy of kio_http to KIO::CC_CacheOnly. This sounds alot simpler than adding 
a proxy to your browser application. This caching policy - sometimes seen as 
offline browsing mode - will prevent khtml from doing any requests unless the 
reload flag is set in the KParts::URLArgs passed to openURL().

But AFAIK, these settings are global to kio_http and there's no way to make 
konqueror avoid reloads when a user request one, so I stopped investigating 
this matter long ago.
