I believe you have linked to a static version?  It does not update here.

> The thing that puzzles me is that response times range widely - the last time I checked, response times ranged from 125 milliseconds to 1,610 milliseconds, with lots of numbers in-between.  Does the Web server cache the response, but not always?  The response is only 343 bytes total, so I can't imagine the network being a bottleneck
Well, they run under IIS/7.0 meaning I have absolutely no idea what goes 
on serverside :)

A possible explanation could be that this is considered low priority so 
the response is just generated whenever the server does not have to do 
anything else.  Another explanation could be that for simplicity reasons 
the code only serves one client at a time, so you have to wait until it 
is your turn.

It appears that it is a sample .NET application.  Hence you should be 
able to look a tthe source code.
