Bloody caching! <g> The guy who presented the ASP portion of my .NET class was terrific and put a lot of emphasis on performance issues. He covered the various caching options pretty thoroughly (at least I thought so, speaking from a fool's paradise) and it still made my brain bleed. If I start doing serious ASP.NET work I know I will need to revisit the whole performance aspect. For now I am deprecating it (one of his favorite words) because it's like drinking water from a fire hose when you're a beginner.
