Austin, Thanks for the reply, but it was terribly vague.
"...thus carries the same fate..."---what fate is that? "...in a particularly direct fashion."---what particular fashion is it, then? Perhaps the "fate" isn't "particularly direct", but surely *something* happens. I need to know what that "something" is, because it isn't documented. * When a network error occurs, what does the readyState change to? * When a network error occurs, is onprogress() called, and with what values? * When I cancel an upload, what does the readyState change to? * When I cancel an upload, is onprogress() called, and with what values? Regardless of whether XHR is well documented, Gears is a Google produce that presumably has some deterministic behavior in the presence of errors. Why can't that be documented? Garret
