<p>This page demonstrates a goog.History object used in an iframe. Loading JS
code in an iframe is useful for large apps because the JS code can be sent in
bite-sized script blocks that browsers can evaluate incrementally, as they are
received over the wire.</p>
<p>For an introduction to the goog.History object, see <a
href="history1.html">history1.html</a> and <a
href="history2.html">history2.html</a>. This demo uses visible history, like
the first demo.</p>
<p>Try following the hash links below, or updating the location with your own
tokens. Replacing the token will update the page address without appending a
new history entry.</p>
