Sounds suppiciously like an unsigned 32 bit int is being used for a
file length somewhere (perhaps even in your own code!) because the
maximum number a uint32 can store is aprox 4 million (:

I was using the form method instead of the upload file method because I also wanted to send other post data. The code is below:

Anyone have any clue as to whats going on here? If I have to use the upload file option, I'd really like send the other post data as well somehow. Thanks.
