How do I write h2o webserver mruby handlers for WordPress multisite?

Question

This is what Apache needs. I like to know how I do this in h2o.

RewriteEngine On
RewriteBase /
RewriteRule ^index\.php$ - [L]

# add a trailing slash to /wp-admin
RewriteRule ^([_0-9a-zA-Z-]+/)?wp-admin$ $1wp-admin/ [R=301,L]

RewriteCond %{REQUEST_FILENAME} -f [OR]
RewriteCond %{REQUEST_FILENAME} -d
RewriteRule ^ - [L]
RewriteRule ^([_0-9a-zA-Z-]+/)?(wp-(content|admin|includes).*) $2 [L]
RewriteRule ^([_0-9a-zA-Z-]+/)?(.*\.php)$ $2 [L]
RewriteRule . index.php [L]

Basically, your Apache file is a bit too much for WordPress.

This should do the trick on H2O:

hosts:
  "www.example.com":
    listen:
      port: 80
    paths:
      "/":
        file.dir: /path/to/doc-root   # serve static files if found
        redirect:                     # if not found, internally redirect to /index.php/<path>
          url: /index.php/
          internal: YES
          status: 307

file.custom-handler:                  # handle PHP scripts using php-cgi (FastCGI mode)
  extension: .php
  fastcgi.spawn: "PHP_FCGI_CHILDREN=10 exec /usr/bin/php-cgi"

access-log: /path/to/the/access-log
error-log: /path/to/the/error-log
pid-file: /path/to/the/pid-file
http2-reprioritize-blocking-assets: ON   # performance tuning option

Hope this helps...
