In my case, the subfolder is “temp.” I have not tested this with multi-level subfolders, but it should work. Note the “QueryParams” array and its use as a param to the SetupAWS method.

In the S3 console, click on your bucket, click on ‘Properties’, then expand the ‘Permissions’ menu. Instead of giving a simple checkbox somewhere to change that default, AWS requires you to add a JSON-formatted ‘bucket policy’ to the bucket. Step 3: Create a bucket policy to make all the content publicīy default when you upload files to an S3 bucket, those files are ‘private’. For instance ‘is not the name of our ‘’ bucket, and if you need to handle those responses also you’ll need to setup another bucket and put in a redirect. If your bucket doesn’t have the same exact name as the hostname the request is coming in as, Amazon will not find the bucket and you’ll see a 404. If you use a CNAME record to point ‘’ to ‘3.’, their S3 service does a primitive version of ‘name-based virtual hosting’, where it looks at the hostname of the incoming request ( ‘’) and assumes that’s the bucket name to use ( ‘s3./’). Once you’ve created your bucket (in our case, ‘’), the URL for that bucket is which also translates to (this assumes that somebody else hasn’t already used the bucket name you selected). Step 2: Setup your DNSĪmazon encourages you to use their Route53 service for DNS hosting and to setup an ‘A’ record, but it was much easier for us to setup a CNAME record and we already have a DNS solution. This will NOT by itself make the bucket appear at ‘’, but it is a required part of the puzzle. This needs to be the exact hostname you’re using. However, if you want to have an S3 bucket that is accessible at ‘’, when you create your bucket you have to name it ‘’. Go to the S3 console and click ‘Create Bucket’. Setting up an S3 bucket is easy, but doing so in a way that allows us to use our own custom hostname is not at all obvious and a bit frustrating, though easy to implement.

Step 1: Setup an S3 bucket that is named with your complete hostname

I won’t detail how to setup a basic AWS account with the billing etc, so if you haven’t done so you’ll need to go to their site and do so.

I was able to string together what we wanted from documentation from several different places, however. Amazon has lots of sample policies and examples, but not for this particular case. What we wanted was an S3 bucket that would be available at a specific hostname – lets call it ‘’ – where a small group of editorial people could upload mp3 files, and for those mp3 files to be publically available via http requests. It was much harder than we expected, mostly because the documentation was confusing and scattered. We recently needed to setup a podcast hosting solution with our own hostname, and we chose to use an AWS S3 bucket.
