As one of the most recognised names in automated website testing, SiteMorse is pleased to announce further testing capability for website developers, mangers and owners by offering 2 additional accessibility AA checks to ensure visitors to your website experience a well performing, problem free complaint experience.

Full details of the tests and a FREE site check are available at www.sitemorse.com

The two additional tests are;

Accessibility AA testing - "norefresh" accessibility diagnostic
W3C Web Content Accessibility Guidelines 1.0 - Checkpoint 7.4 (http://www.w3.org/TR/WCAG10/wai-pageauth.html#tech-no-periodic-refresh)

Accessibility AA testing - "noredirect" accessibility diagnostic
W3C Web Content Accessibility Guidelines 1.0 - Checkpoint 7.5 (http://www.w3.org/TR/WCAG10/wai-pageauth.html#tech-no-auto-forward)

Both the 'noredirect' and 'no refresh' diagnostics are caused by use of the "meta refresh" tag.

This is sometimes referred to as a "client-side" redirect. Its use is contrary to accessibility guidelines (7.4 and 7.5) since it means that the user's browser will, when a hidden timer expires, suddenly jump without warning away from the current page - potentially while they are still in the middle of accessing that page.

The correct way to achieve a redirect is via the use of "server-side" HTTP redirects - for example, the "302 Found" HTTP response code.

Alternatively, a simple link to the new page is acceptable. It is never correct to use a page that refreshes automatically on a timer.
