Everything You Wanted To Know About Caching (mnot.net)

It's still a nice resource, but it's been posted many times before.

You should add the word "web" to the title. There are many other kinds of caching.

Great primer on web caching.

this is good, but somewhat outdated. I haven't used iplanet since 1999. Also SSL/HTTPS is a whole different world.

in the scripts section he says "Generate Content-Length response headers. It’s easy to do, and it will allow the response of your script to be used in a persistent connection. This allows clients to request multiple representations on one TCP/IP connection, instead of setting up a connection for every request. It makes your site seem much faster."

does he mean, for example, when serving up a dynamic php page, where the content might change for each request, you should still generate a content-length header before outputing the content?
