The QueryString collection

The queryString collection contains any information which is added to the URL after the file name. For instance, given a URL of

http://www.trading.com/login.cgi?firstname=harry&lastname=potter

The QueryString collection would contain two items:
firstname with a value of "harry" and
lastname with a value of "potter"
The "?" is used to signal the beginning of the querystring.

A second way of generating a querystring is by using a Form wi ht a Get method instead of a Post method. For example, using the Form from <<<link>>, but instead of using the post method, we will us the GET method.

<form action="IfThenAction.asp" method="GET">
Please choose your preference in month, either March or April:<br>
<input type="text" Name="monthpref"><p>
Please input your preference in location, either East or West<br>
<input type="text" name="location">
<br>
<input type="submit"><input type="reset">
</form>

If we assume the user enters April for MonthPref and East for location, the URL generated from this will look something like:

http://www.yourwebsite.com/IfThenAction.asp?MonthPref=April&Location=East

Retrieving a QueryString

Retrieve All name/value pairs

<% strList=Request.QuerySTring%>

Retrieve a specific item

<% strList=Request.QueryString("iterm_name")%>

Where item_name is the name set in the requesting form. In the above example, we would retrieve MonthPref and Location as follows:

<% strMonthPref=REquest.QueryString("MonthPref") %>
<% strLocation =Request.QueryString("Location")%>
