How do I strip file extensions from URLs with H2O?
I'm trying to use H2O to serve a multi-file PHP website without routing—just having a separate PHP file for every page. The relevant part of my H2O config currently looks like this:
paths:
"/":
file.dir: /home/mysite/www/site/
file.index: [ "index.php" ]
file.custom-handler:
extension: .php
fastcgi.connect:
port: /var/run/php/php7.4-fpm-mysite.sock
type: unix
This works great for the home page. / serves index.php. But for every other page, it requires that I spell out the whole file name in the URL: /other-page.php
Is there an easy way to have H2O route these without needing the extension? I know I can manually list every file as a path in H2O or move every page to its own folder, but I would like something easier and more elegant than that if it exists. I know in Apache this would be a simple RewriteRule, and it's possible with try_files in nginx, but I'm not seeing a way to do this in H2O.

It may be hard to find in the docs, but you can use mruby in H2O to rewrite URLs:
https://h2o.examp1e.net/configure/mruby.html
Unlike Apache, you can use an actual programming language to do the rewriting. This should work for your situation:
reproxy: ON
paths:
"/":
mruby.handler: |
lambda do |env|
if /\/([^?]+)(\?.*)?/.match(env["PATH_INFO"])
return [307, {"x-reproxy-url" => "/#{$1}.php#{$2}"}, []]
end
return [399, {}, []]
end
H2O's documentation says that "H2O recognizes status code 399 which can be used to delegate request to the next handler."
I tested the regex in irb, but I haven't tested it with H2O.
