What is the difference between request query string and requestform collection?

Answer 1

If the HTTP request method is POST, the user submitted data is in the

Request.Form() collection

If the HTTP request method is GET, then user submitted data is in the

Request.QueryString() collection

However, you can still do:

<form method="post" action="page.asp?data=value">

<input type="text" name="txtName" value="Name">

</form>

and

Request.Form("txtName") will contain "Name"

-and-

Request.QueryString("data") will contain "value"

Answer 2

The request query string contains data sent to the server as part of the URL, typically accessed using the Request.QueryString collection in ASP.NET. Meanwhile, the request form collection contains data sent to the server in the body of the HTTP request, such as form data from a POST request, and is accessed using the Request.Form collection in ASP.NET.
