Browser Chomper is an AppleScript script that takes care of those annoying (and dangerous) files that Web browsers create. This version works with Netscape, iCab (though this is disabled by default since iCab can take care of the process itself much more cleanly), and IE (although cookie support with IE is not available). It first looks to see if a compatible browser exist, and then goes on to delete its cookie file, global history file, and cache. It will also auto-empty the trash. See the code for further notes, and comment out the sections pertaining to any files that you would like to keep.
If there are other browsers that you would like supported, please write the code and send it to me (sorry, but doing IE is where I draw the line at doing the development for browsers I don't use). I'll mention your name, unless you wish to be anonymous. Be sure to delete cookies, cache, history, and anything else that might deserve deletion (don't trash prefs, though, just files that can store nasties that others can look at to find out what you've been doing ;->).
If you want to tell me where IE 5.x stores its cookies, I already know: in the Internet Prefs. I'm trying to find a way to get them out and have had suggestions, none of which I found attractive for this script. Code submissions for older versions of IE are welcome, since having just one M$ product on my computer is bad enough.
