don't route certain requests through passenger for single virtual host

[Jay Howard]

I have a Rails application configured using a single Apache virtual host.  All requests to this virtual host go through Passenger and are served by Rails.

Is there a way to flag certain requests (to that virtual host) such that they are *not* handled by Passenger/Rails, and instead are served by Apache itself?

Goal is to reduce load on Rails by preventing it from having to serve these static files.

I realize that I could create a second named virtual host, but I don't have control over the clients and so can't force them to use a new host name for static resources.

Ideally I'd want to use some sort of path regexp to "opt out" certain requests from being served by Passenger/Rails.

Or is there some better way?

Gah.  I didn't realize the "PassengerEnabled" directive could be used inside <Directory> blocks.  Sorry about that.

That said, I copied the example given and requests still seem to be getting sent to Passenger.  With the config below, when I request "https://myserver.mydomain.com/images/foobar.jpg", which doesn't exist, I get a RoutingError in my Rails logs.  We're on 4.0.59 if that matters.

Config:

<VirtualHost *:443>
  SSLEngine on
  SSLCertificateFile {EDITED}
  SSLCertificateKeyFile {EDITED}
  SSLCertificateChainFile {EDITED}
  SSLProtocol All -SSLv2 -SSLv3

  SSLCipherSuite HIGH:!aNULL:!eNULL:!EXPORT:!DES:!MD5:!PSK:!RC4
  Header always set Strict-Transport-Security "max-age=63072000; includeSubdomains;"
  ServerName {EDITED}
  RewriteEngine on

  # limit to allowed methods

  RewriteCond %{REQUEST_METHOD} !^(GET|POST|HEAD|PUT|PATCH|DELETE)
  RewriteRule .* - [F,L]

  DocumentRoot "/websites/myapp/public"

  <Directory "/websites/myapp/public">

Problem solved:

When I turned PassengerHighPerformance to "off" the "PassengerEnabled off" directive started working.  Now it's a question of which I want more:  PassengerHighPerformance, or having static content served by Apache instead of Rails.

Thanks for the update.

I'm not sure how much speed the high performance option gave anyway, you might get a bigger speed bonus by upgrading to 5: https://www.phusionpassenger.com/library/install/apache/migrating/migrating_from_p4_to_p5.html.
