Gets the SPSite object that represents the Microsoft Office Web Apps cache associated with a particular Web application.

Get-SPOfficeWebAppsCache [[-WebApplication] <SPWebApplicationPipeBind>] [-AssignmentCollection <SPAssignmentCollection>]
Get-SPOfficeWebAppsCache [-AssignmentCollection <SPAssignmentCollection>] [-Site <SPSitePipeBind>]

The Get-SPOfficeWebAppsCache cmdlet retrieves the site collection that stores each of the cached renditions for the Word Viewing Service and PowerPoint Service applications. The SPSite object can be used to adjust the expiration of documents cached within that site collection, and to change the maximum size to which the companion cache can grow.


Parameter Required Type Description




Specifies the Web application in which the companion cache is located.




Manages objects for the purpose of proper disposal. Use of objects, such as SPWeb or SPSite, can use large amounts of memory and use of these objects in Windows PowerShell scripts requires proper memory management. Using the SPAssignment object, you can assign objects to a variable and dispose of the objects after they are needed to free up memory. When SPWeb, SPSite, or SPSiteAdministration objects are used, the objects are automatically disposed of if an assignment collection or the Global parameter is not used.

When the Global parameter is used, all objects are contained in the global store. If objects are not immediately used, or disposed of by using the Stop-SPAssignment command, an out-of-memory scenario can occur.




Specifies the identity of the Office Web Apps cache site collection.
