So I am trying to use a flash uploader (specifically uploadify, but tried swfuploader as well) and for some reason the progress isn't being tracked correctly. I am about to give apache a try, but would prefer to use nginx due to its lower memory consumption and speed. Now this isn't an issue with an upload_progress module, since flash itself can track the progress of uploads. Has anyone run into anything similar? Suggestions? Not that it really matters for this cause, but I am using rails.
