Preload Cache Clarification (2 posts)

    Hi All,

    i'd like to ask a clarification about Preload function in WP Super Cache.

    I'm using WP-SuperCache on a low-traffic website, just because my hoster has VERY slow mysql servers. I've enabled the standard cache, with an expiration time of 3600 seconds.

    Now i was thinking to increase the expiration time (24 hours?) to maximize cache hits (i have a very low number of articles, less than 100 and 4 pages).

    But have also enabled Preload. As i've understood, preload ALWAYS keeps a copy of every page on my blog.

    So the question is: if the preload always keeps a cached copy of every page, why should i also set normal cache expiration time?

    And, speaking of articles and pages, what's the link between preload refresh time and normal expiration time? If i have an expire time of 60 minutes and a preload refresh interval of 120 minutes, my preload cache will be rebuilt every 60 minutes, right?

    Thankyou and sorry for my mental confusion

    You set your expiry time based on how often you want the pages on your site to refresh. Regardless of preload status. Put the plugin in "preload mode" and define a preload refresh time and the ordinary garbage collection will only clean up wp-cache files while the preload refresh will refresh everything at the appointed interval.
