Admittedly, that’s very rare.

I know, just a good natured poke :) Plus you could probably take that comment at face value - making use of web caching is definitely an important tool when building a large scale system.

Why is caching out of the window when logged in?

[paulddraper]

It's a page-level cache, and your view on a page depends on username, hidden submissions, point counts, etc.

[dmoy]

votes, things to hide, etc all change the page and prevent serving everything wholesale out of cache

I'm not actually sure, just guessing...
