 * The term cache timeout and garbage collection is really confusing.
 * I searched and searched but it seems the meaning of these terms are really confusing
   to a lot of people.
 * Is it OK to set the Cache Timeout to 604800 seconds. This is 7 Days.
    And then
   set Garbage Collection Scheduler to 3600 Seconds.
 * Does this mean, **after 7 days the WP Super Cache plugin will refresh all my 
   preloaded (cached) pages?**
 * So! If I have 100 pages and posts, will WP Super Cache regenerate (preload) ALL
   100 pages and posts?
 * Now another confusing thing about the “Preload” tab.
    Refresh preloaded cache
   files every 0 minutes. <— This is my setting. If I change this to 30 minutes,**
   does that override my Cache Timeout setting which is set at 7 days?**
