New page

'''Query string''' is one of the techniques in Web applications to send data from one page to another. A query string consists of two parts, field and value, and each of pair separated by ampersand ('''&''').

The '''?'''(question mark in a query string indicates the beginning of a query string and it's value.

Query strings cannot be used to send very long data as there is a limit on the Query string length.

Query strings are visible to the user, hence should not be used to send sensitive information suck as a username and password, unless encrypted.

To retrieve the query string value, use Request object's Query String property.

Request.QueryString(variable)[(index) |.Count]
{| class="wikitable sortable"
|-
! Parameter !! Description
|-
| variable || Required. The name of the variable in the HTTP query string to retrieve
|-
| index || Optional. Specifies one of multiple values for a variable. From 1 to Request.QueryString(variable).Count
|}
