The WDVL: Meta Refresh
|
Sometimes you may want to 'redirect' a request for one URL, to another.
For example, the original URL has become obsolete and you'd like to
direct the user to another URL.
Or perhaps you want to create a slide show effect, where a sequence of
pages is displayed without user intervention.
This page shows how.

- CGI/HTTP Location header if the page is generated by a CGI script.
- Server redirect.
I haven't done this in a long while and don't remember; and the exact
method is server dependent.
- Using the
META tag in the HTML document head.
<META HTTP-EQUIV="Refresh"
Content = "30;
URL=http://wdvl.com/Authoring/HTML/Head/meta.html">
Not all browsers support this; Netscape and Microsoft do.
Be sure to place a link in the old document to the new one.
Some browsers will not do the redirect if they are
busy when the specified time arrives, e.g. loading images,
so the delay time needs to be set high enough to allow that the page
has had enough time to load completely. This may require some
experimentation, preferably over a 28.8 Kbaud modem or slower.
Don't do this gratuitously - it can be annoying for the reader to be
suddenly whisked off to another page (as you are going to be after
this page has been here 30 seconds..).
