i have a bucket and enabled static web site hosting in it.
Say i have only two files in the bucket (index.html) and (error.html)
If a request is hit with test.ht
In the S3 Management Console, open the properties of your bucket and enable the "Static Website Hosting". It will ask you for an index page and an error page and provide you an endpoint for your static website.
