F40: Failure of SC 2.2.1 and 2.2.4 due to using meta redirect with a time limit

Applicability

All pages

This failure relates to:

Description

meta http-equiv of {time-out}; url=... is often used to automatically redirect users. When this occurs after a time delay, it is an unexpected change of context that may interrupt the user.

It is acceptable to use the meta element to create a redirect when the time-out is set to zero, since the redirect is instant and will not be perceived as a change of context. However, it is preferable to use server-side methods to accomplish this. See SVR1: Implementing automatic redirects on the server side instead of on the client side (SERVER) .

Examples

Failure Example 1

The page below is a failure because it will redirect to the URL http://www.example.com/newpage after a time limit of 5 seconds.

<html xmlns="http://www.w3.org/1999/xhtml">
   <head>     
      <title>Do not use this!</title>     
      <meta http-equiv="refresh"
      content="5; url=http://www.example.com/newpage" />   
   </head>   
   <body>     
      <p>       
         If your browser supports Refresh, you'll be       
         transported to our        
         <a href="http://www.example.com/newpage">new site</a>        
         in 5 seconds, otherwise, select the link manually.     
      </p>   
   </body> 
</html>
