Overview

NOTE: This is a middleware that restores the unprocessed URI client requests as is. Usually, nginx-passenger stack unescapes percent encoding in URI and resolve relative paths (ie “.” and “..”). Most of time, processed URI isn’t program. However, if you want to distinguish %2F (ie “/”) from “/”, it is.

Passenger 3.x or later is required.

Use this with following nginx configuration:

... {
   ...
   passenger_set_cgi_param HTTP_X_RAW_REQUEST_URI $request_uri;
}

Usage:

require "racknga"
use Racknga::Middleware::NginxRawURI
run YourApplication
