PUT file to S3 with presigned URL

I\'ve been playing with Amazon S3 presigned URLs all night attempting to PUT a file. I generate the presigned URL in java code.

Ran into this problem as well. We're already tracking when the file is uploaded on the backend, so our work around was to set the content type after the client uploads the file using the Rails app with a call to copy_from.
