> You can use Amazon S3 to host a static website. On a static website, individual webpages include static content. They might also contain client-side scripts.
By contrast, a dynamic website relies on server-side processing, including server-side scripts, such as PHP, JSP, or ASP.NET. Amazon S3 does not support server-side scripting, but AWS has other resources for hosting dynamic websites. To learn more about website hosting on AWS, see Web Hosting.
For example, I have a perl script that generates a set of .html files every night to show new additions to my library. They are static .html files on disk and never modified before the user views them. Just because a perl script (not connected to the web server in any way) made it does not "taint" the HTML so it is not static. The program, or the person, that wrote the HTML does not matter. All that matters is that it's just static unchanging HTML.
If your perl script is saving the HTML to the disk, then yeah, your website is static. If it's generating HTML on the fly, it's dynamic. That's the widely agreed upon meaning, and that's it.
