Subject: Re: net/http - Confirming the right implementation

I wanted to post a followup to this, I finally realized that I was 
trying to use an ssl connection to the uploads. server for the direct 
upload api when that was only needed for obtaining the ClientLogin auth 
key. Replacing that with a normal http:// call solved the issue.
