good to hear, I'm not the only one with those problems :)

for the tests:
well, I did already test it, but the results left me puzzled: I am not sure, how to interpret the testresults, or maybe its a problem of my test environment (server and client on same machine)
so I hoped someone could tell me the facts about uploading right away.

anyway: this is how I tried to test:
* I use a multipart form with an input element of type="file" - I select a big file: 600MB
  | * I press upload
  | * what happens now is:* CPU load of my browser  increases (no networktraffic yet): I suppose the client is building the complete multipart-form request (some seconds)
  |   | * networktraffic starts: I suppose the complete request is now sent to the server
  |   | * my servlet is receiving the request
  |   | * after a short time (1 sec), the commons file upload lib throws a  SizeLimitExceededException exception
  |   | * I catch this exception and in the servlet I send a redirect to an error page
  |   | * the browser is still busy and keeps sendig the request (takes about 30 seconds)
  |   | so I am not sure what happens:* is there a way to inform the browser to abort sending the large request immediately?
  | maybe a redirect is wrong here?
  | * since the client keeps sending data, I suppose the server will still be busy: well at least the bandwidth of the server will still be receiving the data, that the browser is still sending
