^^^^ obviously this doesnt help XHR. however, i'd have to double check, but IIRC you can achieve more XHR connections by opening an iframe and manually setting the frames domain to a higher level (eg, sub.domain.com -> domain.com) ... this was an older way to enable cross-domain communication as you could CNAME any site over to your domain (but it of course requires cooperation from both sides). if you cant open additional XHR from the main frame, im certain you can do it from the iframe, and marshal the results back over. convoluted? yes. but you could create a "data pyjs app" whose only purpose was to perform backend jobs ... you would then mount both apps in the same loader html file. -- C Anthony
