I've got a website that is exhibiting slow performance on the first load and would like to attempt to load it every 5 minutes or so to keep the cache fresh. Are there any simple tools to accomplish this? Scheduled tasks doesn't have quite the time resolution I need. The tricky thing is that this site uses Windows authentication so a wget script won't work. I'm also worried about instantiating a bunch of copies of internet explorer or attempting to kill iexplore.exe tasks blindly.
