// A CGI program uses the following syntax to add cookie information to the HTTP header:
// 
// Set-Cookie:   name=value   
// [;EXPIRES=dateValue]   
// [;DOMAIN=domainName]   
// [;PATH=pathName]   
// [;SECURE]
//
// This function sets a client-side cookie as above.  Only first 2 parameters are required
// Rest of the parameters are optional. If no szExpires value is set, cookie is a session cookie.
//
// Prototype : setCookie(szName, szValue [,szExpires] [,szPath] [,szDomain] [,bSecure])
