<!DOCTYPE HTML PUBLIC "-//IETF//DTD HTML//EN">
<HTML>
<HEAD>
<TITLE>HTML 2.0 DTD: META element</TITLE>
</HEAD>
<BODY>
<H1>META</H1>
<p>
The <META> element is an extensible container for use in identifying
specialized document meta-information. Meta-information has two main
functions:
</p>
<ul>
<li>to provide a means to discover that the data set exists
and how it might be obtained or accessed; and</li>
<li>to document the content, quality, and features of a data
set, indicating its fitness for use.</li>
</ul>
<p>
Each <META> element specifies a name/value pair. If multiple META
elements are provided with the same name, their combined contents--
concatenated as a comma-separated list--is the value associated with
that name.
</p>
<dl>
<dt>NOTE</dt>
<dd>The <META> element should not be used where a
specific element, such as
<a href="title.html"><TITLE></a>, would be more
appropriate. Rather than a <META> element with a URI as
the value of the CONTENT attribute, use a
<a href="link.html"><LINK></a>
element.
</dd>
</dl>
<p>
HTTP servers may read the content of the document
<a href="head.html"><HEAD></a> to generate
header fields corresponding to any elements defining a value for the
attribute HTTP-EQUIV.
</p>
<dl>
<dt>NOTE</dt>
<dd>
The method by which the server extracts document
meta-information is unspecified and not mandatory. The
<META> element only provides an extensible mechanism for
identifying and embedding document meta-information --
how it may be used is up to the individual server
implementation and the HTML user agent.
</dd>
</dl>
<p><strong>Examples</strong></p>
<p>
If the document contains:
</p>
<pre>
<META HTTP-EQUIV="Expires"
CONTENT="Tue, 04 Dec 1993 21:29:02 GMT">
<meta http-equiv="Keywords" CONTENT="Fred">
<META HTTP-EQUIV="Reply-to"
content="fielding@ics.uci.edu (Roy Fielding)">
<Meta Http-equiv="Keywords" CONTENT="Barney">
</pre>
<p>
then the server may include the following header fields:
</p>
<pre>
Expires: Tue, 04 Dec 1993 21:29:02 GMT
Keywords: Fred, Barney
Reply-to: fielding@ics.uci.edu (Roy Fielding)
</pre>
<p>
as part of the HTTP response to a `GET' or `HEAD' request for
that document.
</p>
<p>
An HTTP server must not use the <META> element to form an HTTP
response header unless the HTTP-EQUIV attribute is present.
</p>
<p>
An HTTP server may disregard any <META> elements that specify
information controlled by the HTTP server, for example `Server',
`Date', and `Last-modified'.
