I have already got it working... In my "wrapping" servlet I simply copy the POST-data into a stream of the uploadURL; this creates blobs and calls then "successUrl" where I store the BlobInfo. Wrapping servlet then sends single character to client.
As for your suggestion, like I said, I'm using a Flash component SWFUpload, not a form. There are two issues with current Flash, at least on Windows: 1) It can not send multiple files in single POST/multi-part request. Therefore the component needs to cycle and make multiple requests. (Document/page remains loaded though.) 2) When the uploading request does return empty response (even when the upload was successful) the component goes nuts. Therefore I need the receiving target to send at least "." in response body. Regards J.
