## META

The `META` element can be used to include name/value pairs describing properties of the document, such as author, expiry date, a list of key words etc. The `NAME` attribute specifies the property name while the `CONTENT` attribute specifies the property value, e.g.

        <META NAME="Author" CONTENT="Dave Raggett">

The `HTTP-EQUIV` attribute can be used in place of the `NAME` attribute and has a special significance when documents are retrieved via the Hypertext Transfer Protocol (HTTP). HTTP servers may use the property name specified by the HTTP-EQUIV attribute to create an RFC 822 style header in the HTTP response. This can't be used to set certain HTTP headers though, see the HTTP specification for details.

        <META HTTP-EQUIV="Expires" CONTENT="Tue, 20 Aug 1996 14:25:27 GMT">

will result in the HTTP header:

        Expires: Tue, 20 Aug 1996 14:25:27 GMT

This can be used by caches to determine when to fetch a fresh copy of the associated document.
