I'm pretty sure I got this wrong, particularly the part about clearing the cache before the page is reloaded. That defeats the purpose of a cache. Hmm ... Nic On May 26, 2005, at 6:06 PM, Nicholas Ivy wrote:
So what options do we have to improve caching performance?
1) Perhaps we could use statistics, like a Poisson distribution, to predict how much time is likely to occur between requests to a certain page given the activity we recently recorded [1]. If the predicted wait is greater than 2.5 minutes, don't immediately clear the cache for that page. Instead, wait until there's at least a 50% chance someone will look again. After all, it's likely that no one is looking at it, so why keep the page up-to-date?
