    I have read all the documents related to wp-super-cache. But I still can’t figure out what is garbage collection and what is expired pages.

    Also it would be helpful if someone can tell me how wp-super-cache works. As per my understanding, after enabling this plugin, a cached-HTML page is created when ever some one visits my page. And this cached page is rebuild when ever someone comments or whenever I update the post.

    Am I correct? If so, what is garbage collection and expired pages thn?

    Thanks in advance.

  • Expired pages are simply out of dated pages. “Expired” ??

    Garbage collection is the means of removing those expired pages every once in a while. In a perfect world it would run the garbage collection all the time but then your server would get bogged down.

    You’re right about how supercache works, but some pages don’t get comments and will only be removed from the cache by the GC.

    So does this mean that the pages will expire every 3600 seconds (default) and garbage collection will delete those pages and wp-super-cache will rebuild the static HTML page again?

    Why do we want the page to expire on time bases, wouldn’t it be efficient if the page is only rebuilt when there is a comment or there is any change in the post? Otherwise rebuilding all pages every 3600 seconds will eat a lot of CPU usage. Correct me if I am wrong.

    Yeah, but the only pages that will rebuild are those that are visited.

    It’s better to keep the number of cached files down. The readme.txt explains some of the reasoning behind how it works.
