AutoPOST is a Web site/utility that can automatically submit a form, complete with data. Your form submission is packaged into one extended URL, which you can use anywhere you’d use a normal URL– a bookmark, a link, a non-form-supporting browser. Whenever you access the URL, the form is automatically submitted. AutoPOST supports both GET and POST form submissions (POST submissions are routed through a special AutoPOST script when called, transparent to the user).
