There is a real test.com.  For examples, please use the .example TLD or the 
example.com SLD:

<http://tools.ietf.org/html/rfc2606>

If you have a problem with a Web site, however, it is of course best to post 
the real URI.

I do not think `obj' is ever going to be `undefined' at this line.  You can 
just as well assign `true', or skip `found' and only work with `obj' (which 
you might want to initialize with `null').

See also jsx.net.http.Request.prototype._getXHR() in 
<http://pointedears.de/websvn/filedetails.php?repname=JSX&path=%2Ftrunk%2Fhttp.js> 
(a bit slow currently).

You should reconsider that approach.  There should be an event for the 
successfully loaded ActiveX control which you can add an event listener for, 
or the control can execute code itself.
