HTTP Message Headers
Meta elements of the form can be used as alternatives to HTTP headers. For example, would tell the browser that the page "expires" on June 21, 2006 at 14:25:27 GMT and that it may safely cache the page until then. The HTML 4.01 specification optionally allows this tag to be parsed by HTTP servers and set as part of the HTTP response headers, but no web servers currently implement this behavior. Instead, the user agent emulates the behavior for some HTTP headers as if they had been sent in the response header itself.

Famous quotes containing the word message:
“The whole idea of image is so confused. On the one hand, Madison Avenue is worried about the image of the players in a tennis tour. On the other hand, sports events are often sponsored by the makers of junk food, beer, and cigarettes. What’s the message when an athlete who works at keeping her body fit is sponsored by a sugar-filled snack that does more harm than good?”
—Martina Navratilova (b. 1956)
