Detecting a 302 redirect to an XmlHttpRequest call?

[enaeher]

Hello,

I'd like to be able to detect whether the browser is receiving an HTTP
status 302 redirect when handling the response to an Ajax call. I can
see the 302 status code clearly with LiveHTTPHeaders in Firefox, but
every time the XmlHttpRequest onreadystatechange handler is called, the
status property is '200'. It seems like the 302 is being handled by the
browser somewhere upstream of my JavaScript.

(I know that this has been asked once before -- that I've found -- in
this group, but it seems like the only response misunderstood the
question.)

Thanks,

--Eli

302's are redirected automatically, there's no way to detect it.
