Do static hosted websites on S3 typically include "www" in their names?

Static hosted websites on Amazon S3 do not inherently require "www" in their names; this is a matter of configuration rather than a rule imposed by S3 itself.

By default, when you create a static website hosted on S3, the bucket name must exactly match the URL that users will use to access the website. If a user wants to access the website using "www," the bucket must be named accordingly (for example, "www.example.com"). If the bucket is named "example.com," it will not automatically redirect requests from "www.example.com" to "example.com."

The "www" prefix is not included unless the user specifically sets it up by creating a bucket with that name and configuring the appropriate DNS settings or redirection rules using AWS services, such as Route 53. This flexibility allows site owners to choose how they want their URLs structured, emphasizing that the inclusion or exclusion of "www" is purely a configuration choice rather than a requirement from S3.
