About  Office_Viewing_Service_Cache  site collection -/sites/Office_Viewing_Service_Cache


This is the OOB default SharePoint2010 behavior  to cache the documents/ppts  while rendering in the browser from any site collection within the specific web application.



Background History  about Office web app:



The Office Web Apps’ cache is the back-end store that is responsible for housing images, HTML, JavaScript, and XAML resources once they have been created for a document. Each time a document is converted into a set of these resources, the resources are stored in the Office Web Apps’ cache. When a request for a document comes into SharePoint, the cache is checked to see if the document had been previously requested and rendered. If it has, and the cached document resources are up-to-date for the document, then the document request is served from the cache instead of engaging Office Web Apps to convert and re-render it. Serving document resources from the Office Web Apps’ cache can yield significant performance improvements over scenarios where no cache is employed.



The Office_Viewing_Service_Cache  site collection is a standard Team Site, and it is the location where resources are stored after the conversion and rendering of either a Word or PowerPoint document by Office Web Apps.

The Office Web Apps’ cache takes the form of a single site collection for each Web application within a SharePoint farm. When Office Web Apps is installed and configured in a SharePoint environment, a couple of new timer jobs are installed and run regularly within the farm. One of those timer jobs, the Office Web Apps Cache Creation timer job, ensures that each Web application where Office Web Apps is running has a site collection
