Content created using server-side scripting to store preferences.
This technique is not referenced from any Understanding document.
The objective of this technique is to provide a mechanism for users to select a preference for an alternate conforming version of a Web page.
Providing preferences to allow users to view conforming alternate versions can be accomplished in several ways. One common method is to provide a link which triggers a server-side process that sets a session or persistent cookie that the Web server uses to modify the page or redirect the user to the alternate version. Other methods include providing user-specific choices that are stored as part of the user's login information for a system where users sign in to access a Web page or service.
Users requiring an alternate version will need the mechanism provided in the non-conforming page to be accessible in order to find and use it. The mechanism itself should conform to the accessibility level being claimed.

- Check that Web pages are displayed according to the selected preference.
- Check that when the preference(s) are set, the Web page conforms as claimed.
- Verify that the resulting page is a conforming alternate version for the original page.
