I suppose I wasn't very clear in my initial description. I'm looking for something that will test all the links on my site to make sure that they are all working. We have some 20,000 or so different links, and going through that many by hand would take weeks. For standard HTML sites there is software that basically "crawls" the website like a search engine would and simply verifies that all the links work. This software won't work on Spaces because of how the pages are dynamically created.
