uploading 1MB file over slow connection - GAE request timeout

[Tolick]

For simplicity reasons let's assume someone tries to upload 1MB file
over modem connection (56k, for example). That would take ~2 minutes
which will trigger DeadlineExceededException.

If someone solved the problem via standard means (without Applets or
other heavy browser side components, I mean) - please share your
experience!

Hi,

The 30 second deadline applies only to time spent executing your code. Your code does not begin executing until the client has finished sending the request body, so the speed of the uploader does not matter.

Nick: If someone were to download a 1MB file over a 56k modem,
AppEngine would kill the process every time, is that correct?

Locke,
Wrong ! it will not as my experience tells and Nick above is
explaining

Mr. Milon,

Mr. Johnson explained that UPLOADS do not start your 30s counter until
they complete. My question is about DOWNLOADS in which your app begins
execution and THEN sends data to the user, executing all the while.

Please review the RFC 2616 if you are confused.

Hi Locke,

The same applies to downloads: The response is not sent to the user until your script finishes executing, and thus the time the user takes to download the response is not factored into your overall execution time.
