hi clueless,
i am clueless too

The
main browser cache's storing place on a standard Windows computer is the following folder:
Code:
C:\Documents and Settings\Clue Less\Local Settings\Temporary Internet Files\
It's heavily used by Internet Explorer and many other Windows programs (which need to connect to the internet), especially Microsoft programs. Your system displays the folder in 2 different modes and it's a little tricky to control the modes. By default, you should see a long list of files with their url's...
Other browsers are free to use other hdd locations (folders) to store temporary internet files ("browser cache"), and the default view might be plain (without url's).
It will be difficult to give a general statement or observation on whether the situation with websites and their FLV's has changed since there are too many websites with streaming media. Maybe there's some heavy browser cache user?
