Pairs with https://github.com/caddyserver/caddy/pull/4436.
I could split these changes in two, some changes should only land in 2.5.0, but others are pure documentation that could be pushed live now. But 🤷♂️ I think it's fine for these to wait until 2.5.0, what's another month or whatever? 😅
I somehow forgot to add this to the docs when I implemented it a while back. Someone asked a question on the forums where this was the solution, and I noticed it wasn't documented.
* docs: Some cleanup, some v2.4.0 additions
- Add `abort` directive docs
- Add a note in `handle` to cross-link to `handle_path`
- Add another example in `handle_errors` that shows how an `expression` matcher can be used to pair with it
- Add a cat emoji to handle_errors because 😸
- Add `file_server` to one of the `php_fastcgi` examples, it's rare that you'll ever use it without `file_server` so might as well include it there
- Add a TOC to `reverse_proxy` cause it's such a long page. Maybe we'll add one to other pages as well, but TBD
- Clarify the upstream address stuff a bit after some discussion in https://caddy.community/t/reverse-proxy-with-multiple-different-upstreams-with-paths/11512/12 and mention `rewrite` as the alternative
- Use the `{re.*.*}` shortcut in the Caddyfile matcher docs, links to the placeholder mapping to let people trace where that comes from
* docs: Revise the `handle` cross-linking, add another example
* docs: Bump minimum Go version to 1.15
* docs: A bunch more additions since v2.3.0
I went through the whole list of commits here: https://github.com/caddyserver/caddy/compare/v2.3.0...ec3ac84
* docs: Review feedback
* docs: Link to https://golang.org/doc/install, better instructions
