It seems the memory cache cannot be cleared without a restart of Safari. I've tested this: running the "Empty Cache" functionality clears the disk cache (that is at $HOME/Library/Caches/com.apple.Safari/Cache.db) immediately, but loading pages (eg. by clicking on links on webpages) that I've visited before I cleared the cache does not result in new downloads of the various content (eg. images). I used the Charles Debugging Proxy, but any other proxy can do. Please, leave a comment if you know a method for clearing the memory cache without restarting Safari. (In case you'd suggest: the "Reset Safari" functionality is no better than "Empty Cache" ... at least regaring the memory cache).

It seems that the QuickTime plugin in Snow Leopard (/Library/Internet Plugins/QuickTime Plugin.plugin) cannot be forced to open movies (eg. the ones at trailers.apple.com) in the old player, "QuickTime Player 7" (which is an optional component and once installed, it's at /Applications/Utilities/QuickTime Player 7). If you don't know why this is necessary, then you didn't try to open a QuickTime movie (*.mov) from a website yet. But all is not lost yet, because there's a workaround: exit QuickTime X and start QuickTime Player 7 _before_ you'd open the movie in your browser. It appears that in case there's already a running instance of a QuickTime player, the browser plugin will use that one (if there's no running player instance, then it'll always start QuickTime X).
