C# Class FiftyOne.Foundation.Mobile.Redirection.RequestRecord

Class used to convert a HttpRequest into a single long value that is almost unique for the requesting device. Two devices that share the same external IP address and HTTP headers will calculate to the same long value so it may not always be unique. The number of handsets that fall into this category should be sufficiently small enough for it not to present a practical problem. The date and time the request was received is also recorded to enable out of date records to be removed from the list.

Public Methods

Method	Description
CompareTo ( object obj ) : int	Compares one request to another to determine if they are the same.

Protected Methods

Method	Description
Read ( BinaryReader reader ) : void
RequestRecord ( ) : System	Creates a new empty instance of RequestRecord class.
RequestRecord ( BinaryReader reader ) : System
RequestRecord ( HttpRequest request ) : System	If the IP address is IPv4 (4 bytes) then use the ip address as the high order bytes of the value and the hashcode as the low order bytes. If the IP address is IPv6 (8 bytes) then covert the bytes to a 64 bit integer. If anything else which we can't imagine use a hashcode of the string value.
RequestRecord ( RequestRecord recordToCopy ) : System	Constructs a new instance of RequestRecord class. Copies the values of the RequestRecord provided to the new instance.
Write ( Stream stream ) : void

Private Methods

Method	Description
SetHashCode ( byte buffer, HttpRequest request ) : void	Adds the hashcode of the relevent header fields as the low order bytes of the array.
