>>>I have a small ASP.NET application used by a number of customers. Yesterday one of the customers brought up an issue that it takes too much time on loading the first page. I tested on my PC (I use IE 6.0) and I can see the issue. It takes about 10 seconds to load the first page the first time. The good news is that after the first time, each subsequent load of the page is very fast (almost instantaneous). So it seems like there is some kind of caching issue here. My question is, is it the caching on the web server or Internet Explorer? What can I do to improve the speed of loading the main page the very first time?

IIRC do it on the production server. That is how I have done it.
