Got an e-mail from the team at Port80 Software in San Diego. They have a compression and caching solution for IIS, which although not my development platform of choice, is heavily used in the Fortune 1000, mainly due to the requirement from these firms to contract with a vendor with enterprise support programs.
The link below takes you to their variety of tools that check the cacheability and compressibility (this a word?) of your pages.
They also have a blog — [200 OK]. Drop by and check them out — there is a very interesting discussion on TIME_WAIT states going on, an oft-forgotten little tweak that is available for high-performance Web servers.
