Change the browser URL without navigating away?

[Paul Neave]

Yahoo! has launched a beta of it's new mapping application:

http://maps.yahoo.com/beta/

It's based in Flash, but it uses JavaScript. I'm curious about one
feature, though - when you pan about the map, the URL in the address
bar of your browser changes to match your current location. How have
they done this? I thought calling window.location.href = "etc"; would
reload the page, navigating away from the current URL. Yahoo! have
managed to do this without the page changing. This is a very useful
technique for DHTML/AJAX/Flash technology and I'd love to know how
they've done it.

Many thanks,
Paul.

An example of non-parallel thinking, combined with 3W recommendations
sent to the hell.
Link hash part (anchor name) #blah-blah-blah does not lead to
navigation away from the current page. Unresolved anchor names do not
lead anymore neither to a page shift not to an error: tested on IE 6.0
and FF 1.0.7
Opera 8.1 fails on it (did not check yet Opera 8.5, cannot check Safari
and Konqueror)

document.location.hash = "Write all what you need";

Ingenious! Another exellent example to myself to read less about
standards or rely on some previous experience. Only continues
experiments on concrete systems have practical value.

Only the hash part of the url is changing. You can do this as follows:

parent.location.hash = 'hello';

The actual URL http://maps.yahoo.com/beta/ before the '#' cannot be changed without a page reload.

Thanks guys - for those interested, here are some workarounds that use
this method for bookmarking and using the back button in Flash:
