Is it possible to limit the cache size of Safari, so it cleans up after itself?

[Nobody]

No way in Safari itself to limit the cashe size, but there may be some shareware or freeware that will let you enable it, there is a way to empty the cache in safari if you did not know and maybe an applescript could be written and set as a login item to empty it for you whenever you logged in. Someone here who knows applescript might be able to do that.

I made an alias of the Safari cache folder and placed it in a convient location (the dock). Then once a day I delete all the cache files. It really eats up disk space unless you empty the folder regularly. /forums/ubbthreads/images/graemlins/smile.gif

how about saving yourself some time and just using the "empty cache" feature under the safari menu?

[griffman]

A hint on my site today explained how to disable the cache -- delete ~/Library/Caches/Safari (while Safari is NOT running), then create an empty text document and save it as Safari (no extension) in the ~/Library/Caches folder.
Safari will no longer be able to cache pages.
-rob.

I just stuck a cache deactivator option into Safari Enhancer for anyone interested.
