FPCConnectionLimitPolicy

The FPCConnectionLimitPolicy object represents a connection limit policy. A connection limit establishes how many transport-layer protocol connections can exist at one time for a single user. Examples of transport-layer protocols are TCP and UDP. The policy designates connection limits for default users and connection limits for special users.

When the TCP connection limit for a user is reached, no additional TCP connections are allowed for the user.

When the UDP connection limit for a user is reached and the user attempts to make an additional UDP connection, the first UDP connection that the user made is closed, and the new connection is established.

A typical special user would be a Web server, which would require many more connections than a default user.

Special users can be defined using computer sets.

The FPCConnectionLimitPolicy object is typically accessed through the ConnectionLimitPolicy property of an FPCArrayPolicy 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

This object has no methods.

Properties

The FPCConnectionLimitPolicy object has the following properties.

Property	Description
DefaultLimit	Gets an FPCConnectionLimit object that specifies the connection limits for a default user.
Enabled	Gets or sets a Boolean value that indicates whether the connection limit policy is enabled.
RulePerSecondLimit	Gets or sets the maximum number of connections that can be created for a rule during one second.
SpecialComputerSets	Gets an FPCRefs collection that contains references to the FPCComputerSet objects defining the computer sets to which the special connection limits apply.
SpecialLimit	Gets an FPCConnectionLimit object that specifies the connection limits for a special user.

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.
VendorParametersSets	Gets an FPCVendorParametersSets collection that can hold sets of custom data for extending the object.

Remarks

This object implements the IFPCConnectionLimitPolicy interface.
