/*
* name = Required parameter. String value that does not include any of the following 
*				characters: semi-colon, comma, white space, and the "@" character. Non-string 
*				values will be converted to a string.
* duration = Integer value that defines how many hours the cookie should persist for. If 
*						this parameter isn't specified, a session cookie is created.
* path = String value specifying the path that the cookie is in scope for. If this 
*				parameter isn't specified, the cookie is only available for the directory that 
*				it was created in, and any of its subdirectories. The most common value for this 
*				parameter is "/", which specifies the root of the 
*				website. Giving the cookie root scope makes it available globally throughout 
*				your website.
* domain = String value. This parameter is only necessary 
*					for sites that run multiple sub domains.
* secure = Boolean value. If this parameter is "true", the cookie 
*					created will only be transmitted under Secure Sockets Layer (SSL).
