URL parameters
A URL parameter is a name/value pair appended to a URL. The parameter begins with a question
mark (?) and takes the form
is separated by an ampersand (&). The following example shows a URL parameter with two
name/value pairs:
http://server/path/document?name1=value1&name2=value2
URL parameters let you pass user-supplied information from the browser to the server. When a
server receives a request, and parameters are appended to the URL of the request, the server puts
the parameters at the disposal of the requested page before serving that page to the browser.
In this example, imagine that the application is a web-based storefront. Because the developers of
the site want to reach the widest possible audience, they have designed the site to support foreign
currencies. When users log in to the site, they can select the currency in which to view the prices
of the available items.
The browser requests the page

parameter
Currency="euro"
amounts retrieved be displayed as the European Union euro.
The server temporarily stores the URL parameter in memory.

The report.cfm page retrieves and uses the parameter to retrieve the cost of items in euros. These
3
monetary amounts can either be stored in a database table of different currencies, or converted
from a single currency associated with each item (any currency supported by the application).
The server sends the report.cfm page to the browser, and displays the value of items in the
4
requested currency. When this user terminates the session, the server destroys the value of the
URL parameter, freeing up server memory to hold the requests of new users logging in to
the site.
