In-Depth Information
Kumquats are currently trading at $1.96 per pound.
The financial wizards among you may have noticed that, with some spe-
cial software tricks on the server side, you can update the price of kum-
quats in the document so that it acts like a ticker-tape machine, with
the latest kumquat commodity price updated every 15 seconds. Refreshing with a different document
Instead of reloading the same document repeatedly, you can tell the
browser to load a different document dynamically. You do so by adding
that document's URL after the delay time and an intervening semicolon
in the <meta> tag's content attribute. For example:
<meta http-equiv="Refresh"
content="15; URL=">
causes the browser to retrieve the next.html document from the web server after having displayed the current docu-
ment for 15 seconds. Cycling between documents
Keep in mind that the effects of the Refresh <meta> tag apply only to the
document in which it appears. Hence, to cycle between several docu-
ments, you must include a Refresh <meta> tag in each one. To achieve
the effect, set the content value for each document in the cycle with a
URL which points to the next document, and the last document pointing
back to the first one to complete the cycle.
