impl: Redirect paths starting with `/public/` when not Authed

[5HT2]

Ideally, when an Auth header is not provided, if a user is given a link such as https://cdn.frogg.ie/public/pdfs/, or a specific file, it should redirect to https://cdn.frogg.ie/pdfs/ (or the specific file), if it exists.

This is preferable over being handed a 404, and if you have the URL of an existing file you could already remove the /public/ from the URL yourself.

The only downside I could see this having is it being confusing in some cases?? Maybe? Like, if you thought you had provided an Auth and weren't expecting it to serve non-Authed content.

• The only cases where this really matters could easily be mitigated by only redirecting on GET and nothing else, to avoid rewriting real edit requests.

• Maybe this be configurable??

• Maybe config options allow enabling this only for folder paths?
