<META>
The <META> Tag is used to embed information not contained in other HTML Tags or
elements, for example to identify, index, and catalog documents. There are two main
commands, MAIN and HTTP-EQUIV. The <META> Tag goes between the <HEAD> Tag and usually after the <TITLE> Tag:
<head>
<title></title>
<meta>
</head>
One use of the <META> Tag is to reload or redirect an HTML Page. This is an example of a Client
Pull.
<META HTTP-EQUIV="Refresh" CONTENT="60">
The CONTENT is in seconds and in this case would reload the page after 1 minute.
If you add a ;
URL=http://www.quadzilla.com, it would automatically go to
another URL after 5 seconds. I'm sure you seen "This page has moved, automatically
sending you there" pages, this is how it's done.
<META HTTP-EQUIV="Refresh"
CONTENT="5; URL=http://www.quadzilla.com">
You might want to include information about the document,
such as keywords for indexing, the name of the author, and so on. This can be done with
the NAME followed by CONTENT:
<META NAME="author" CONTENT="D.J.
Quad">
<META NAME="keywords" CONTENT="html reference, guide, help, tags,
web">
<META NAME="editor" CONTENT="Notepad">
The attribute NAME refers to user-selected names, while HTTP-EQUIV means that the value has a real equivalent header in the HTTP protocol.
Again, this is only really useful given tools for processing these data. At present, there
are quite a few search engines and other tools that take advantage of <META>.
