Proxy spec for Apache2.4 and php7-fpm

[Lindsay Haisley]

I'm using the recipe for Proxy via handler at the PHP-FPM - Httpd Wiki, the code for which is:

• # Defining a worker will improve performance

  # And in this case, re-use the worker (dependent on support from the fcgi application)

  # If you have enough idle workers, this would only improve the performance marginally

  <Proxy "fcgi://localhost:9000/" enablereuse=on max=10>

  </Proxy>

  <FilesMatch "\.php$">

      <If "-f %{REQUEST_FILENAME}">

          # Pick one of the following approaches

          # Use the standard TCP socket

          #SetHandler "proxy:fcgi://localhost/:9000"

          # If your version of httpd is 2.4.9 or newer (or has the back-ported feature), you can use the unix domain socket

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

      </If>

  </FilesMatch>

I'm using unix sockets, so the references to TCP/IP ports is spurious, and the code, which I've modified to support my requirements here, works well. My question regards the <Proxy> directive to tune PHP-FPM. Is it sufficient to simply drop the port number so that the line becomes:

<Proxy "fcgi://localhost/" enablereuse=on max=10>

In the appropriate SetHandler invocation the target for the "fcgi://" scheme is pretty much a no nevermind and makes no difference, as I've discovered from experimentation and found mentioned in several places. What should be used for "fcgi://" in the <Proxy> directive? Or does it matter, as it doesn't for SetHandler?

It seems it doesn't matter and that as long as the fgdi: spec is lexically legal, it's ignored. I'm using "fcgi://*, in both the Proxy and SetHandler specs and everything is working fine.
