Absolute vs relative URLs to generated RSS files

[TysonMN]

The coding-blog-plugin documentation for RSS says to link to the feed files using an absolute URL.

RSS files are generated in 3 formats:

Atom, which will be accessible on https://.coding.blog/_feed.atom
RSS2.0, which will be accessible on https://.coding.blog/_feed.rss
JSON Feed, which will be accessible on https://.coding.blog/_feed.json

I would prefer to use a relative URL that would work both when locally hosting and when deployed to my live site.

In its current form, I couldn't test the link locally before publishing. Then after publishing and some change, the link still points the old (deployed) file.

In both cases, my workaround was to directly open the generated files to inspect them. I have no workaround for testing the link before deploying the first time.
