	Change History (most recent first):

	<14>	05/28/99	KA		convert NewPtr to MMNew and DisposePtr to MMFree
	<13>	05/05/99	KA		our return length was off by two!
	<12>	04/29/99	KA		use new encode/decode calls
	<11>	04/23/99	KA		fixed a bug in ParsingGenericNBPURL
	<10>	04/11/99	KA		added MakeGenericNBPURL
	<09>	04-07-99	sns		MemMgr.h -> NSLMemMgr.h
	<08>	03-30-99	KA		incorporated changes for Steve
	<07>	03/26/99	sns		explicit namespace (for carbon d9)
	<06>	02/25/99	KA		call DecodeHTTPString when parsing out a url
	<05>	01/26/98	KA		added checks for valid pointers in NewGenericNBPURL
	<04>	11/09/98	KA		added IsValidATZone
	<03>	11/06/98	KA		added some missing #includes
	<02>	11/06/98	KA		moved EncodeHTTPString and DecodeHTTPString to URLUtilities.cp
	<01>	11/06/98	KA		added EncodeHTTPString and DecodeHTTPString and converted to .cp file
	<4>		10/15/98	KA		took out conversion of AFPServer to afp
