== The Environment

def check_env(env)
      ## The environment must be an true instance of Hash (no
      ## subclassing allowed) that includes CGI-like headers.
      ## The application is free to modify the environment.
      assert("env #{env.inspect} is not a Hash, but #{env.class}") {
        env.instance_of? Hash
      }

      ##
      ## The environment is required to include these variables
      ## (adopted from PEP333), except when they'd be empty, but see
      ## below.

      ## <tt>REQUEST_METHOD</tt>:: The HTTP request method, such as
      ##                           "GET" or "POST". This cannot ever
      ##                           be an empty string, and so is
      ##                           always required.

      ## <tt>SCRIPT_NAME</tt>:: The initial portion of the request
      ##                        URL's "path" that corresponds to the
      ##                        application object, so that the
      ##                        application knows its virtual
      ##                        "location". This may be an empty
      ##                        string, if the application corresponds
      ##                        to the "root" of the server.

      ## <tt>PATH_INFO</tt>:: The remainder of the request URL's
      ##                      "path", designating the virtual
      ##                      "location" of the request's target
      ##                      within the application. This may be an
      ##                      empty string, if the request URL targets
      ##                      the application root and does not have a
      ##                      trailing slash. This value may be
      ##                      percent-encoded when I originating from
      ##                      a URL.

      ## <tt>QUERY_STRING</tt>:: The portion of the request URL that
      ##                         follows the <tt>?</tt>, if any. May be
      ##                         empty, but is always required!

      ## <tt>SERVER_NAME</tt>, <tt>SERVER_PORT</tt>:: When combined with <tt>SCRIPT_NAME</tt> and <tt>PATH_INFO</tt>, these variables can be used to complete the URL. Note, however, that <tt>HTTP_HOST</tt>, if present, should be used in preference to <tt>SERVER_NAME</tt> for reconstructing the request URL.  <tt>SERVER_NAME</tt> and <tt>SERVER_PORT</tt> can never be empty strings, and so are always required.

      ## <tt>HTTP_</tt> Variables:: Variables corresponding to the
      ##                            client-supplied HTTP request
      ##                            headers (i.e., variables whose
      ##                            names begin with <tt>HTTP_</tt>). The
      ##                            presence or absence of these
      ##                            variables should correspond with
      ##                            the presence or absence of the
      ##                            appropriate HTTP header in the
      ##                            request.

      ## In addition to this, the Rack environment must include these
      ## Rack-specific variables:

      ## <tt>rack.version</tt>:: The Array [1,0], representing this version of Rack.
      ## <tt>rack.url_scheme</tt>:: +http+ or +https+, depending on the request URL.
      ## <tt>rack.input</tt>:: See below, the input stream.
      ## <tt>rack.errors</tt>:: See below, the error stream.
      ## <tt>rack.multithread</tt>:: true if the application object may be simultaneously invoked by another thread in the same process, false otherwise.
      ## <tt>rack.multiprocess</tt>:: true if an equivalent application object may be simultaneously invoked by another process, false otherwise.
      ## <tt>rack.run_once</tt>:: true if the server expects (but does not guarantee!) that the application will only be invoked this one time during the life of its containing process. Normally, this will only be true for a server based on CGI (or something similar).
      ##

      ## Additional environment specifications have approved to
      ## standardized middleware APIs.  None of these are required to
      ## be implemented by the server.

      ## <tt>rack.session</tt>:: A hash like interface for storing request session data.
      ##                         The store must implement:
      if session = env['rack.session']
        ##                         store(key, value)         (aliased as []=);
        assert("session #{session.inspect} must respond to store and []=") {
          session.respond_to?(:store) && session.respond_to?(:[]=)
        }

        ##                         fetch(key, default = nil) (aliased as []);
        assert("session #{session.inspect} must respond to fetch and []") {
          session.respond_to?(:fetch) && session.respond_to?(:[])
        }

        ##                         delete(key);
        assert("session #{session.inspect} must respond to delete") {
          session.respond_to?(:delete)
        }

        ##                         clear;
        assert("session #{session.inspect} must respond to clear") {
          session.respond_to?(:clear)
        }
      end

      ## The server or the application can store their own data in the
      ## environment, too.  The keys must contain at least one dot,
      ## and should be prefixed uniquely.  The prefix <tt>rack.</tt>
      ## is reserved for use with the Rack core distribution and other
      ## accepted specifications and must not be used otherwise.
