mod_proxy_fcgi unix domain socket syntax question on Apache documentation

["Rose, John B" <jbrose@xxxxxxx>]

Looking at the documentation on this page  ...

https://httpd.apache.org/docs/2.4/mod/mod_proxy_fcgi.html

The documentation says "With this syntax, the hostname and optional port following fcgi:// are ignored." regarding this example ...

ProxyPassMatch "^/(.*\.php(/.*)?)$" "unix:/var/run/php5-fpm.sock|fcgi://localhost/var/www/"

Why are they in the example if they are ignored?

Are they also ignored here?

SetHandler  "proxy:unix:/path/to/app.sock|fcgi://localhost/"

Thanks

John
