At first sight, this concept sounds much simpler than the 
existing one. Also it seems that this saves a lot of space 
(cache size approx. 1/6 of the old one).

Unfortunately, I can not open the ZIP file in WinZIP (lots 
of "Invalid Filename <http://bla.bla.com/robots.txt>).

Would it be necessary to switch to another Zip tool to view 
the cache?
