If all browsers followed the W3 standards the world would be a better place...
They say "...field value consists of a single absolute URL."
^^^
I think they mean URI because the example says "absoluteURI", not URL.
An absolute URI is
/some/location
But so is
http://www.somehost.com/some/location
Both are valid URIs and both absolute. One is more qualified than the other.
A relative URI is
some/location
which is incorrect, and not what I meant in my message.
Which brings us to the next point...
By using relative *URLs* such as /some/location, you avoid changing
the location field in the browser window, which is often desired. If
you use an absolute *URL*, the location field changes to the absolute
URL.
You can try it with a simple perl script CGI.
#!/usr/bin/perl
print "Location: /some/location/\n\n";
or
#!/usr/bin/perl
print "Location: http://somehost.com/some/location/\n\n";
