<h3>dojo.undo.browser test (dojo.io.bind() with bookmarking)</h3>
See the Dojo Book entry for
<a href="http://manual.dojotoolkit.org/WikiHome/DojoDotBook/DocFn1">Back Button and Bookmarking</a>.
<p>This page tests the dojo.undo.browser back/forward integration with dojo.io.bind(),
and dojo.undo.browser's bookmarking facility. For a back/forward test without bookmarking,
see <a href="test_browser.html">test_browser.html</a>.</p>
<p>The buttons that start with "XHR" use
dojo.io.bind to do some XMLHTTPRequest calls for some test data, and they
also define back/forward handlers, so dojo.io should use dojo.undo.browser
add to history tracking.</p>
<p>To test the bookmarking facility:</p>
<ul>
<li>Click on one of the buttons below.</li>
<li>Save the resulting URL as a bookmark.</li>
<li>Close the browser window, or navigate to a different page.</li>
<li>Click on the bookmark to jump to that state in the page</li>
</ul>
<p>Other notes:</p>
<ul>
<li>Don't test this page using local disk for MSIE. MSIE will not
create a history list for iframe_history.html if served from a file:
URL. The XML served back from the XHR tests will also not be properly
created if served from local disk. Serve the test pages from a web
server to test in that browser.</li>
<li>Safari 2.0.3+ (and probably 1.3.2+): Only the back button works OK
(not the forward button), and only if changeUrl is NOT used (so it <b>will not</b>
work for this test page, since it is using bookmarking -- changeUrl).
When changeUrl is used, Safari jumps all the way
back to whatever page was shown before the page that uses
dojo.undo.browser support.</li>
<li>Opera 8.5.3: Does not work.</li>
<li>Konqueror: Unknown. The latest may have Safari's behavior.</li>
