[Mulgara-general] firefox bug and server config

[Gregg Reynolds]

Hi,

I'm working on a simple web page and javascript for exploring Mulgara.  I
seem to have run into a firefox bug, whereby a GET transaction is completed
(readyState == 4) but the status == 0.  I'm sending the get request to a
vanilla mulgara instance on localhost:8080 that I know works.  In
LiveHTTPHeaders I can see the request and response, both of which look
fine.  But the XMLHttpRequest object seems to be discarding the data.  This
is on OS X 10.5.8, FF 3.5.2.

I've been beating my head on this for about eight hours now and I'm
completely flummoxed (how I hate software!).  My suspicion however is that
this might be connected to the new support (
https://developer.mozilla.org/En/HTTP_access_control) for the
CORS<http://dev.w3.org/2006/waf/access-control/>
standard.  I.e., if the mulgara response were to include the
"Access-Control-Allow-Origin" header, it might possibly maybe work.  (See it
in action, with LiveHTTPHeaders on, at
http://arunranga.com/examples/access-control/simpleXSInvocation.html  Dunno
what else to try at this point.

The problem is I have no idea how to configure Jetty and I'm hoping somebody
on the list does and is willing to save me the trouble of learning.  ;)

FWIW, the little doo-dad I'm building (which could compete with the iTQL
CLI, if I could just get Firefox to cooperate!) is at
http://bitbucket.org/gar/mulligan/overview/ in case anybody's interested.
Very simple, just some fancy jQuery stuff that exposes the HTTP request
structure and sparql/tql query string.  It worked yesterday, on a windows
machine.  Honest!  But to debug the xmlhttprequest problem I'm just using a
mimimal webpage.

Thanks,

gregg
