Re: Postback mechanism in asp.net

Tech-Archive recommends: Repair Windows Errors & Optimize Windows Performance

asp.net checks if __VIEWSTATE is in the form data to determine if IsPostback is true.

asp.net pages can use either the get or post method, so thats not a reliable method. a post means the form data follows the headers, a get means its contained on the url as args. form data is passed as name value pairs. the content-type header specifies if there is form data.
