You doesn't got errors, because you are running in debug. Got the same problem while working on my speedtest project. So for the questions.
I believe that Adobe wants to have it so that you can NOT use URLLoader to upload a file without interaction. I just think that they happened to not do it in the best way and you can get around it depending on how exactly you are using the URLLoader to upload the file (if you put a filename in the POST for the URLLoader it should error out, but you can get around that by Base64 encoding the file and sending that with the URLLoader to php).
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
