FPCCacheRule Object

The FPCCacheRule object represents a single cache rule. A cache rule defines cache policy for all content or specific content groups, including:

How objects are provided from the cache.
Whether objects should be stored in the cache.
The size of objects that can be stored in the cache.
Whether Secure Sockets Layer (SSL) responses will be stored in the cache.
Whether content supplied after user authentication by the Web server will be stored in the cache.
The configuration settings in an FPCFTPCacheConfiguration object for FTP caching.
The configuration settings in an FPCHTTPCacheConfiguration object for HTTP caching.

This object is an element of an FPCCacheRules collection.

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 FPCCacheRule object defines the following method.

Method	Description
SetSizeBound	Sets the minimum or maximum size of the objects that can be cached.

Properties

The FPCCacheRule object defines the following properties.

Property	Description
CacheAuthenticatedContent	Gets or sets a Boolean value that indicates whether content supplied after user authentication by the Web server or an upstream proxy server will be cached.
CacheBITSContent	Gets or sets a Boolean value that indicates whether content received using the Background Intelligent Transfer Service (BITS) will be cached.
CacheContentForOfflineBrowsing	Gets or sets a Boolean value that indicates whether content for offline browsing with response code 302 or 307 will be cached.
CacheDynamicContent	Gets or sets a Boolean value that indicates whether dynamic responses will be cached even if their headers mark them as not cacheable.
CacheSSLResponses	Gets or sets a Boolean value that indicates whether responses are cached when the incoming or outgoing request uses SSL.
Description	Gets or sets the description of the rule.
DestinationDomainNameSets	Gets an FPCRefs collection that contains references to the FPCDomainNameSet collections defining the domain name sets included in or excluded from the request destinations to which the rule applies.
DestinationSelectionIPs	Gets an FPCSelectionIPs object that specifies the complete set of destination IP addresses to which the rule applies.
Enabled	Gets or sets a Boolean value that indicates whether the rule is enabled.
FTPConfiguration	Gets an FPCFTPCacheConfiguration object that defines the configuration settings for FTP caching.
HTTPConfiguration	Gets an FPCHTTPCacheConfiguration object that defines the configuration settings for HTTP caching.
IsDefault	Gets a Boolean value that indicates whether the rule is preinstalled and cannot be deleted.
Name	Gets or sets the name of the cache rule.
NeverCacheResponse	Gets or sets a Boolean value that indicates whether responses will never be cached.
ObjectSizeLimit	Gets the maximum size of an object that can be cached.
ObjectSizeLimitEnabled	Gets a Boolean value that indicates whether the object size limit is enabled.
ObjectSizeLimitUnits	Gets a value from the FpcSizeUnits enumerated type that specifies the units in which the ObjectSizeLimit property is expressed.
Order	Gets the ordinal position of the rule in the list of cache rules, which corresponds to their order of application.
URLSets	Gets an FPCRefs collection that contains references to the FPCURLSet collections defining the URL sets included in or excluded from the request destinations to which the rule applies.
UseCacheCondition	Gets or sets a value from the FpcCacheAction enumerated type that specifies the conditions under which an object should be retrieved from 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 IFPCCacheRule and IFPCCacheRule2 interfaces.

Requirements

Client	Requires Windows Vista or Windows XP.
Server	Requires Windows Server 2008.
Version	Requires Forefront Threat Management Gateway (TMG).
IDL	Declared in Msfpccom.idl.
