I'd would like to ask of those familiar with using WP Super Cache.
Our organization is using WP for mainly serving data to our clients. We do not maintain an interactive Blog, we just serve data, so no one other than our admin actually logs into the site.
We need to use WP Super Cache to avoid overloading the shared hosting service we use.
This is our situation. We update our data at midnight local time, and need to have this data available to our clients at 1 minute after midnight local time. If we us WP Super Cache how soon will the cache update so our clients have this data at 1 minute after midnight (or very shortly thereafter). Remember they are just viewing our site like any casual surfer, and not actually logging in, so their log in process will not update any cached pages.
I hope I've explained my situation well as a neophyte user of WP and my limited knowledge of caching.
