how this works (redirection??)

Many times you go to a website, say xyz.org
The moment it opens up in browser window, the address is changed to
www.xyz.com in the title bar.

Basically, how is this achieved ?

Am I looking at an apache configuration ?
Or is this an html trick ?

A simple redirect will (usually) do it:

<META HTTP-EQUIV="refresh" CONTENT="0;URL=http://my.newplace.com/">

Please use example.com for example urls. That's what it's there for. :-)

Usually by sending a 301 (moved permanently) or 302 (found) HTTP status
code to the browser, pointing to the other site. Others in the 3xx
series could also be used, as appropriate.

> Am I looking at an apache configuration ?

Assuming your site is hosted with Apache, of course. ;-) Yes, it can be
done on the web server. It can also be done in a server-side scripting
language, such as PHP:

header('Location: http://www.example.com/');

> Or is this an html trick ?

It can (kind of) be done in HTML, as per Neredbojias' post, but is
better handled server-side.

this will cause first the oldplace.com to load
then newplace.com would load.

try yahoo.org - they take you to yahoo.com without double loading..

is this a dns trick or what?

You should really be doing the opposite, redirecting
http://www.example.com to http://example.com. The www subdomain is a
rather nasty hack which should have never been invented, and is
deprecated on the modern Web. See http://no-www.org/.

Works great.

In the OP's example, we are talking about 2 different domains - one is
..org, the other .com.

No arguments there. The only time I type www in to access a site is if
I've already tried without the www and it didn't work.

> See http://no-www.org/.

I agree with their philosophy for the most part, but there are more
serious issues on that site that the presence or absence of www, like
javascript popup links, grey on white text that is really hard to read,
inappropriate link text...

It is done by sending a 301 status, generated by the web server:

08/11/05 10:21:45 Browsing http://yahoo.org
Fetching http://yahoo.org/ ...
GET / HTTP/1.1
Host: yahoo.org
Connection: close
User-Agent: Sam Spade 1.14

HTTP/1.1 301 Moved Permanently
Date: Thu, 11 Aug 2005 14:22:16 GMT
Location: http://www.yahoo.com/
Connection: close
Transfer-Encoding: chunked
Content-Type: text/html; charset=iso-8859-1

The document has moved <A HREF="http://www.yahoo.com/">here</A>.<P>

Please don't do that.

Actually, I can't think of a valid reason for doing it.
