Reload doesn't refresh sources with framesets
 

I've noticed that when you reload a page with framesets you pay frequent visit to, reload doesn't refresh sources for each frame element.

For example, a case like this: there's a web page consisting of frame A and frame B, where you visit very frequently. Consequently these page (frame) sources are constantly stored in your cache. And in such a case, when you reload such a page, each frame isn't refreshed - cached sources are always loaded. The frames remain not updated until each frame is loaded independently. They ARE updated after you flush the cache, but with the default cache settings they are never updated.
