How populate Request.FormData collection


How the Request.FormData property is populated? What should be sent in the request (query parameters or request body) in order to have this name/value collection to be populated?

I tried finding the code that does it and couldn’t do it.

Thank you

FormData is populated with a HTTP POST using the application/x-www-form-urlencoded Content-Type, i.e. this is what browsers do by default for HTML <form method=POST />.
