The Backlog property specifies the maximum size of the
queue used to manage pending connections to the service. If the
property is set to value which exceeds the maximum size for the
underlying service provider, it will be silently adjusted to the
nearest legal value. There is no standard way to determine what the
maximum backlog value is.
This property should be set to the desired value before the
Start method is called. The default backlog value
is 5 on all Windows platforms. The Windows Server platforms support
a maximum backlog value of 200.
Note that this property does not specify the total number of
connections that the server application may accept. It only
specifies the size of the backlog queue which is used to manage
pending client connections. Once the client connection has been
accepted, it is removed from the queue. Set the
MaxClients property to specify the maximum number
of clients that may connect with the server.
