W3 Total Cache + S3 + Cloudfront. [closed]

what WordPress/site files normally go into the S3 bucket in order to get optimal use as a CDN?

Normally the defaults should suffice i.e.,

You’d want to check these options under the “General” section:

• Host attachments

• Host wp-includes/ files

• Host theme files

• Host minified CSS and JS files

• Host custom files

And under “Advanced” section:

• Modify “Theme file types to upload” to something like this:

  *.css;*.js;*.gif;*.png;*.jpg;*.ico;*.ttf;*.otf,*.woff,*.eot,*.svg
  

That should do it.
