Editing Meta element (section)

==Redirects==
[[Meta refresh]] elements can be used to instruct a [[Web browser]] to automatically refresh a Web page after a given time interval. It is also possible to specify an alternative [[Uniform Resource Locator|URL]] and use this technique in order to [[URL redirection|redirect]] the user to a different location.
Auto refreshing via a META element has been deprecated for more than ten years,<ref name=":0">{{Cite web|url=http://www.w3.org/TR/1999/WD-WAI-PAGEAUTH-19990226/wai-pageauth-tech|title=Welcome to the Virtual Mall!|website=www.w3.org|access-date=2018-10-15}}</ref> and recognized as problematic before that.<ref name=":0" />

The W3C suggests that user agents should allow users to disable it, otherwise META refresh should not be used by web pages.
For Internet Explorer's security settings, under the miscellaneous category, meta refresh can be turned off by the user, thereby disabling its redirect ability.
In Mozilla Firefox it can be disabled in the configuration file under the key name "accessibility.blockautorefresh".<ref>[https://web.archive.org/web/20090602225157/http://kb.mozillazine.org/Accessibility.blockautorefresh Accessibility.blockautorefresh] mozillaZine, archived June 2, 2009 from [http://kb.mozillazine.org/Accessibility.blockautorefresh the original]</ref>

Many web design tutorials also point out that client-side redirecting tends to interfere with the normal functioning of a Web browser's "back" button. After being redirected, clicking the back button will cause the user to go back to the redirect page, which redirects them again. Some modern browsers seem to overcome this problem however, including [[Safari (web browser)|Safari]], [[Mozilla Firefox]] and [[Opera (web browser)|Opera]].{{citation needed |date=April 2011}}

Auto-redirects via markup (versus server-side redirects) are not in compliance with the [[World Wide Web Consortium|W3C's]] – [[Web Content Accessibility Guidelines|Web Content Accessibility Guidelines (WCAG) 1.0]] (guideline 7.5).<ref name=WCAG>W3C Recommendation (May 5, 1999), [http://www.w3.org/TR/1999/WAI-WEBCONTENT-19990505/#gl-movement Web Content Accessibility Guidelines 1.0 – Guideline 7].
