I haven't seen this documented. I only know what I was told by the project
manager of the ASP development team at Microsoft when I was working on
msn.com. He was helping us tweak the performance of the site. We needed to
do everything we could because it is the third highest traffic site on the
internet, and the highest traffic ASP application. We were calling the
JavaScript eval method from VBScript, but he thought it was definitely a bad
idea on a site with that kind of load.
The "Web front ends caching pages" thread that is going on right now has a
few more details on caching. George Reilly points out the article at:
http://support.microsoft.com/support/kb/articles/q221/7/90.asp for
information on how ASP keeps track of when to update the cached page because
of changes in a file.

Hi Don, do you have any more info about this mechanism... perhaps an MSDN
article of some kind, I'd like to know.
