Thanks for help, I think I can do this here too. There's one thing that I can't see how works. You said on step 9, that after I do request.send(blob), I receive a get parameter that says it is an upload. It means that it works similar with an upload by html form? So, what's the reference to that file after the upload on server side? and my problem is that I need to send more than one file at once and also send extra data from some input text. The only solution would be Iterate and send the files one by one and then send the data? I couldn't send everything that I want in a one simple request?
