The Request.QueryString Property

Introduction

The Request.QueryString property can be used to retrieve the values from a form, which is posted via the GET method. The query string stores the values in a pair combination after the ? sign in the URL. It looks like this: Elementname=Value. Even Google use this method for this search string. The URL of Google looks like this when searching for the string “TopXML”.

http://www.google.com/search?hl=en&ie=UTF-8&q=TopXML

Example

The following example shows a simple textbox. The value of the textfield is passed via the Get method and retrieved via the Request.QueryString property. When entering the value “Sonu” in the textfield the query string looks like this:

http://localhost/request_object_properties/request_object_property_querystring_example.asp?username=Sonu

<%

            if Request.QueryString("username") <> "" then

                        Response.Write "Welcome " & Request.QueryString("Username")

            end if

%>

<form method="get">

Username: <input type="textfield" name="username"/>

<input type="submit">

</form>
