Did you mean context rather than content?

NameValueCollection nvc = context.Request.Form;

Your <input> has runat="server", but your <form> does not.

Either your page will return an exception indicating that the control must be placed inside a form tag with runat="server"; or the <form> tag you've shown is nested inside an existing server form.

Nested forms are not valid or supported. Their behaviour is undefined; they might sort-of work in some browsers, but that is subject to change at any time.

Note: It's strictly forbidden to nest a form inside another form. Nesting can cause forms to behave in an unpredictable manner based on the browser that is being used.
