FPCCache Object

The FPCCache object is used to administer all cache configuration settings in a Forefront TMG array. Most details of the cache configuration are accessed through the CacheConfiguration and ScheduledContentDownload properties of this object. The CacheConfiguration property retrieves an object of type FPCCacheConfiguration, and the ScheduledContentDownload property retrieves an object of type FPCScheduledContentDownload.

The FPCCache object also provides access to an FPCCacheContents object, which permits greater control over caching through its FetchUrl method. This method is used to actively download a specific URL directly to the cache and to set the time that the cached object will be stored in the cache. The FetchUrl method can also be used to delete an object from the cache.

The FPCCache object is accessed through the Cache property of an FPCArray object.

Inheritance

This object inherits from the FPCPersist object, which contains methods and properties related to the persistent storage of an object's data. They include methods for exporting the object's data to and importing it from an XML document.

Methods

The FPCCache object does not define any methods.

Properties

The FPCCache object defines the following properties.

Property	Description
CacheConfiguration	Gets an FPCCacheConfiguration object that provides access to the cache configuration settings for the array.
CacheContents	Gets an FPCCacheContents object that provides a method for downloading content to the cache.
ScheduledContentDownload	Gets an FPCScheduledContentDownload collection that contains the prefetching tasks for the cache.

Methods Inherited from FPCPersist

Name	Description
CancelWaitForChanges	Cancels the registration established by the WaitForChanges method (for use in C and C++ programming only).
CanImport	Returns a Boolean value that indicates whether the object's properties can be imported from the specified XML document.
Export	Recursively writes the stored values of all the properties of the object and its subobjects to the specified XML document.
ExportToFile	Recursively writes the stored values of all the properties of the object and its subobjects to the specified XML file.
GetServiceRestartMask	Retrieves a 32-bit bitmask of the FpcServices enumerated type that specifies which services need to be restarted for currently unsaved changes to take effect.
Import	Recursively copies the values of all the properties of the object and of its subobjects from the specified XML document to persistent storage.
ImportFromFile	Recursively copies the values of all the properties of the object and of its subobjects from the specified XML file to persistent storage.
LoadDocProperties	Provides the XML document's properties so that you can know what information can be imported from the document.
Refresh	Recursively reads the values of all the properties of the object and of its subobjects from persistent storage, overwriting any changes that have not been saved.
Save	Recursively writes the current values of all the properties of the object and its subobjects to persistent storage.
WaitForChanges	Registers to wait for an event indicating that the contents of the object have changed (for use in C and C++ programming only).

Properties Inherited from FPCPersist

Name	Description
PersistentName	Gets the persistent name of the object. The persistent name of an object is a name that is unique for the object at the respective level of the COM object hierarchy.
VendorParameterSets	Gets an FPCVendorParametersSets collection that can hold sets of custom data for extending the object.

Interfaces for C++ Programming

This object implements the IFPCCache interface.

Requirements

Client	Requires Windows Vista or Windows XP.
