1) This is not an ASP.NET feature. When you press a submit button, the
browser sends a HTTP request to the server. This request contains the value
of all non disabled, named fields that are in your form.
2) The viewstate is an hidden field (as such it is posted by the browser
when the submit button is hit allowing the server to read the viewstate).

ASP.NET is a clever hack but just uses client side what was available
previously (HTML, HTTP).
