// **********************************************************************
//		Name:			Type:		Description:
//		--------		--------	-------------------------
//		name			string		The name of the cookie
//
//		value			string		The value of the cookie
//
//		expires			string		When the cookie should expire. If this value is not set,
//									the cookie is never written to the hard drive and 
//									disappears when the browser is closed.
//
//		path			string		By default, a cookie is only available to pages in the 
//									same directory as the page that created it, as well as  
//									any subdirectories. Setting this attribute makes the 
//									cookie visible in other directories as well. If this 
//									value is set to '/', the cookie is available on the 
//									entire site.
//
//		domain			string		By default, a cookie is only available to pages on the
//									same web server as the page that created it. Setting 
//									this attribute makes the cookie visible to other web
//									servers as well. The domain of the cookie cannot be set
//									to a domain other than the domain of your server.
//
//		security		boolean		Boolean value that determines how the cookie is 
//									transmitted over the network. By default, cookies are 
//									insecure and trasnmitted over normal, insecure HTTP 
//									connections. If the security of the cookie is set to be 
//									secure, it is only transmitted when the browser and 
//									server are connected via HTTPS or another secure protocol.
//
//		Notes:			This function currently does not set the domain or 
//						security attributes. If the cookie must be available
//						across multiple domains, this function will need to be
//						modified.
