Stream upload to S3 fails quoting unsupported HTTP version.

[kulkarnih]

I'm trying to stream a file to an S3 instance. I get the generic error "Unable to initiate stream upload [Invalid upload ID". But the response from S3 indicates unsupported HTTP version.

<?xml version="1.0" encoding="UTF-8"?>
<Error>
<Code>HttpVersionNotSupported</Code>
<Message>The HTTP version specified is not supported.</Message>
<RequestId>788D2319F7FE4EAF</RequestId>
</Error>

On further testing, found out that this happens only for files with space in the name.

The objectName needs to be urlencoded before making the request.

// Send the initiate request
var req = this.client.request('POST', this.objectName + '?uploads', this.headers),
