Request.QueryString

ASP Reference

Request.QueryString

Like the Request.Form collection, Querystring returns information posted using the GET method in a form, or from referencing a variable directly when calling a page.

For example 'myascript.asp?variable=contentsofvariable' could retrieve the value of 'myvariable' by using Request.QueryString("myvariable").

Like other ASP collections, you can reference QueryString using : Request.QueryString("itemname"), Request.QueryString.Item("itemname") and Request.QueryString([key]).

Also notable is the use of 'Request.QueryString' on its own to grab all the information (non-variable parsed) sent to the script, and also the 'Count' property, which returns the number items in the collection. QueryString is not recommended for obtaining a lot of data, or for sensitive information. For this use Request.Form.
