I am using PHP/JavaScript/MySQL on XAMPP to develop the prototype.I need to use session that in-turn makes use of cookies. Here is the question,how do I know whether or not the user's browser supports cookies or not.For detecting javascript, I use \[code\]<noscript></noscript>\[/code\]. Please correct me if I am wrong.Thank you
