Control of Dokuwiki's
caching operations. This is important to wiki-page authors, as sometimes a page gets cached by Dokuwiki on the server, and needs to be purged. Remember, what the author sees may not be what others see.
This is different than your browser's cache, which may occassionally need to be flushed. For example, when the
PHP global memory limit is exceeded, that wiki-page can't be displayed, even if the
PHP global memory limit is changed on the server. You would need to flush your browser's cache to load and view the wiki-page.
