POSTing to an ASP? ASP’s Request.Form requires application/x-www-form-urlencoded.
If you’re writing a web client of some sort that is trying to push data at an ASP based page via a POST request, you need to set up your HTTP headers correctly. To get ASP to parse the request body into the Request.Form collection the content-type must be “application/x-www-form-urlencoded” and the content-length must be set.
“application/x-www-form-urlencoded” is the default value for the HTML <form> element’s enctype attribute.
