[support] Anonymous Pages that Don't Cache, Even for Anonymous Users

Gang, After some weird load spikes and reboots on my dedicated server, I'm trying to set up better monitoring of my server. At websitepulse.com I can easily set up performance testing on a web page which should give me a sense of server load. (I can also do fancier stuff like write a script that returns key words based on server load that websitepulse will look for and then alert me about. But that will take some scripting.) So what I want is a Drupal page, available anonymously, that won't get cached by Drupal. Is that true for search result pages? Any other ideas? I could implement this on a D6 or D7 site. Thanks, Shai
