<P>This metabase property specifies the expiration of HTML document content by returning the value to the browser in the HTML file header. The browser compares the value of this property with the current date to determine whether to display a cached page or to request an updated page from the server. This property can be made relative, or dynamic, by using the format D,<I>#SecondsUntilExpiration</I> (with 0xFFFFFFFF indicating no expiration date). It can also be absolute, with the format S,<I>ValidGMTString</I>.</P>
