On this question, there were 5 answers about 20 minutes ago, but the main page claimed it only had one answer (even after refreshing); It had only 1 upvoted answer at the time. Now it has 5 answers still, 3 upvoted, and the main page now shows 5 answers. Is this a result of caching, or some function that I am unable to infer?
I had a similar issue here, the problem being that it was caching the older versions of the page. If you're behind a proxy, the proxy can also serve up stale versions of the page.
