AWS proxy module

Implements proxying of authenticated requests to S3.

  server {
    listen     8000;

    location / {
      proxy_pass http://your_s3_bucket.s3.amazonaws.com;

      aws_access_key your_aws_access_key;
      aws_secret_key the_secret_associated_with_the_above_access_key;
      s3_bucket your_s3_bucket;

      proxy_set_header Authorization $s3_auth_token;
      proxy_set_header x-amz-date $aws_date;
    }

    # This is an example that does not use the server root for the proxy root
    location /myfiles {

      rewrite /myfiles/(.*) /$1 break;
      proxy_pass http://your_s3_bucket.s3.amazonaws.com/$1;

      aws_access_key your_aws_access_key;
      aws_secret_key the_secret_associated_with_the_above_access_key;
      s3_bucket your_s3_bucket;
      chop_prefix /myfiles; # Take out this part of the URL before signing it, since '/myfiles' will not be part of the URI sent to Amazon  


      proxy_set_header Authorization $s3_auth_token;
      proxy_set_header x-amz-date $aws_date;
    }

  }

Request signing & Amazon Cloudfront Service

If Nginx is behind Amazon's CloudFront CDN service, you need to add this setting :

proxy_set_header x-amz-cf-id "";

into nginx.conf in order to clear X-Amz-Cf-Id header before signing the request to Amazon S3 bucket.

More info here :

Credits:

Original idea based on http://nginx.org/pipermail/nginx/2010-February/018583.html and suggestion of moving to variables rather than patching the proxy module.
