// Coded by ACN for AHC 15/04/2003 
// Last Updated by ACN on 28/05/2003 
// * fixed a pName typo resulting in failure to save cookies
//
// Updated by CJL 12/01/2004
// * 'exp' variable changed to 'expHour' because exp is now a reserved word.
// * fixed 'setCookie' error, 'pExpires=' : should be 'expires='
