If I understand correctly, W3TC caches a given page after the first time a visitor loads it, or I can set it to cache pages automatically using the Cache Preload section.
Now, I also have this Sitemap Generator installed, which crawls all the pages on my site to create a sitemap. (I use it instead of a sitemap plugin because I have thousands of pages that are created by another plugin, which are not technically in my WP database.)
So here's my question. Since that Sitemap Generator crawls all the pages on my site, does that mean W3TC is caching them at that time? If so, wouldn't running W3TC's Cache Preload be redundant and therefore unnecessary?
