I am using HttpContext.Current.Cache to store some values in a web service
method.
I have a page in the same web application that simply dumps the contents of
Page.Cache to the screen.

Why is it that every time I refresh the dump page, different items appear?
Nobody is using the application or calling any web services except me.
What's even more mysterious, sometimes items that disappeared hours ago come
back again!

I've tried it on two machines, both running framework 1.1.
Everything works as you would expect on an XP Pro machine running IIS 5.1.
Once I started testing on a 2k3 server machine running IIS 6, the Cache
started hidding items and bringing them back randomly.

This problem is very frustrating. Any advice would be great.
