The Site Preview System Drupal module is a framework for previewing a site with a set of conditions active. Here is a video to introduce you to what the module does. SPS was developed out of the LSD CSI project as part of a suite of modules.

The Site Preview System works by accepting conditions, generating a list of override revisions and altering the page to display the correct revision on the page. Modules that came out of the CSI project
