Remarks

If the property is omitted, the name property should be used to identify the meta-information. The httpEquiv property is not case-sensitive. Developers using the httpEquiv and content attributes to refresh documents from alternate URLs should treat the value of content as untrusted data. For more information, please see Security Considerations: Dynamic HTML.

As of Windows Internet Explorer 8, the httpEquiv attribute also supports a value of x-ua-compatible, which allows developers to specify the document compatibility mode that Windows Internet Explorer should use to display a webpage. To do this, set the content attribute to a String value containing a comma-delimited list of one or more of the following values.
