Where can I find more Documentation for cache plugin?

[Fabian Lopez]

I trying to find more information about the cache plugin.

My question is how often the refresh is calculated and if the time is based on the server or when the page that has the plugin is visited.

Will this help? https://studio.plugins.atlassian.com/wiki/display/CACHE/Confluence+Cache+Plugin

P/s: if the site is under brief maintenance, try the google cache.

Brendan's answer is correct. There are some macro options and conditions that can affect that - see the plugin page referenced above and comment there if you need more detail.
