+ ## (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 [1,1], 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?(:delete)
+ }
+
+ ## clear;
+ assert("session #{session.inspect} must respond to clear") {
+ session.respond_to?(:clear)
+ }
+ end
+
+ ## <tt>rack.logger</tt>:: A common object interface for logging messages.
+ ## The object must implement:
+ if logger = env['rack.logger']
+ ## info(message, &block)
+ assert("logger #{logger.inspect} must respond to info") {
+ logger.respond_to?(:info)
+ }

+
+ # = Sendfile
+ #
+ # The Sendfile middleware intercepts responses whose body is being
+ # served from a file and replaces it with a server specific X-Sendfile
+ # header. The web server is then responsible for writing the file contents
+ # to the client. This can dramatically reduce the amount of work required
+ # by the Ruby backend and takes advantage of the web server's optimized file
+ # delivery code.
+ #
+ # In order to take advantage of this middleware, the response body must
+ # respond to +to_path+ and the request must include an X-Sendfile-Type
+ # header. Rack::File and other components implement +to_path+ so there's
+ # rarely anything you need to do in your application. The X-Sendfile-Type
+ # header is typically set in your web servers configuration. The following
+ # sections attempt to document
+ #
+ # === Nginx
+ #
+ # Nginx supports the X-Accel-Redirect header. This is similar to X-Sendfile
+ # but requires parts of the filesystem to be mapped into a private URL
+ # hierarachy.
+ #
+ # The following example shows the Nginx configuration required to create
+ # a private "/files/" area, enable X-Accel-Redirect, and pass the special
+ # X-Sendfile-Type and X-Accel-Mapping headers to the backend:
+ #
+ # location ~ /files/(.*) {
+ # internal;
+ # alias /var/www/$1;
+ # }
+ #
+ # location / {
+ # proxy_redirect off;
+ #
+ # proxy_set_header Host $host;
+ # proxy_set_header X-Real-IP $remote_addr;
+ # proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
+ #
+ # proxy_set_header X-Sendfile-Type X-Accel-Redirect;
+ # proxy_set_header X-Accel-Mapping /files/=/var/www/;
+ #
+ # proxy_pass http://127.0.0.1:8080/;
+ # }
+ #
+ # Note that the X-Sendfile-Type header must be set exactly as shown above. The
+ # X-Accel-Mapping header should specify the name of the private URL pattern,
+ # followed by an equals sign (=), followed by the location on the file system
+ # that it maps to. The middleware performs a simple substitution on the
+ # resulting path.
+ #
+ # See Also: http://wiki.codemongers.com/NginxXSendfile
+ #
+ # === lighttpd
+ #
+ # Lighttpd has supported some variation of the X-Sendfile header for some
+ # time, although only recent version support X-Sendfile in a reverse proxy
+ # configuration.
+ #
+ # $HTTP["host"] == "example.com" {
+ # proxy-core.protocol = "http"
+ # proxy-core.balancer = "round-robin"
+ # proxy-core.backends = (
+ # "127.0.0.1:8000",
+ # "127.0.0.1:8001",
+ # ...

+ # proxy-core.allow-x-sendfile = "enable"
+ # proxy-core.rewrite-request = (
+ # "X-Sendfile-Type" => (".*" => "X-Sendfile")
+ # )
+ # }
+ #
+ # See Also: http://redmine.lighttpd.net/wiki/lighttpd/Docs:ModProxyCore
+ #
+ # === Apache
+ #
+ # X-Sendfile is supported under Apache 2.x using a separate module:
+ #
+ # http://tn123.ath.cx/mod_xsendfile/
+ #
+ # Once the module is compiled and installed, you can enable it using
+ # XSendFile config directive:
+ #
+ # RequestHeader Set X-Sendfile-Type X-Sendfile
+ # ProxyPassReverse / http://localhost:8001/
