Example of information stored in session variables

You’re working on a site with a large audience of senior citizens. In Dreamweaver, add two links to the Welcome

screen that let users customize the size of the site’s text. For larger, easy-to-read text, the user clicks one link, and for

regular-size text, the user clicks another link.

Each link has a URL parameter called

fontsize that submits the user’s text preference to the server, as the following

Macromedia ColdFusion® from Adobe example shows:

<a href="resort.cfm?fontsize=large">Larger Text</a><br>

<a href="resort.cfm?fontsize=small">Normal Text</a>

Store the user’s text preference in a session variable and use it to set the font size on each page the user requests.

Near the top of the destination page, enter the following code to create a session called

font_pref that stores the

user’s font size preference.

ColdFusion

ASP and ASP.NET

<% Session("font_pref") = Request.QueryString("fontsize") %>

When the user clicks the hypertext link, the page sends the user’s text preference in a URL parameter to the desti-

nation page. The code on the destination page stores the URL parameter in the

font_pref session variable. For the

duration of the user’s session, all the pages of the application retrieve this value and display the selected font size.
