title: Uploading to Amazon-S3 via AFNetworking
body: <p>I'm having difficulty uploading files to S3 via AFNetworking.  When I attempt to upload, I get callbacks indicating a small percentage of the file is uploaded, then the callbacks cease, and one or two minutes later I get a timeout message.</p>
  
  <p>I'm using <a href="https://github.com/AFNetworking/AFAmazonS3Client" rel="nofollow">AFAmazonS3Client</a> but it seems like a pretty straight forward subclass of AFHTTPClient so it seems unlikely the problem lies there.  Since I'm new to both AFNetworking and S3, I'm pretty sure the problem is typing this message :)</p>
  
  <p>I've downloaded the AWS-IOS SDK and was able to post a picture from their sample code without a problem.  So I don't think its a misconfiguration of my S3 account.</p>
