+A request/response rewriting HTTP proxy. A Rack app. Subclass `Rack::Proxy` and provide your `rewrite_env` and `rewrite_response` methods.
+
+Example
+-------
+
+```ruby
+class Foo < Rack::Proxy
+
+  def rewrite_env(env)
+    env["HTTP_HOST"] = "example.com"
+
+    env
+  end
+
+  def rewrite_response(triplet)
+    status, headers, body = triplet
+
+    headers["X-Foo"] = "Bar"
+
+    triplet
+  end
+
+end
+```
+
+### Disable SSL session verification when proxying a server with e.g. self-signed SSL certs
+
+```ruby
+class TrustingProxy < Rack::Proxy
+
+  def rewrite_env(env)
+    env["rack.ssl_verify_none"] = true
+
+    env
+  end
+
+end
+```
+
+The same can be achieved for *all* requests going through the `Rack::Proxy` instance by using
+
+```ruby
+Rack::Proxy.new(ssl_verify_none: true)
+```
+
+Using it as a middleware:
+-------------------------
+
+Example: Proxying only requests that end with ".php" could be done like this:
+
+```ruby
+require 'rack/proxy'
+class RackPhpProxy < Rack::Proxy
+
+  def perform_request(env)
+    request = Rack::Request.new(env)
+    if request.path =~ %r{\.php}
+      env["HTTP_HOST"] = "localhost"
+      env["REQUEST_PATH"] = "/php/#{request.fullpath}"
+      super(env)
+    else
+      @app.call(env)
+    end
+  end
+end
+```
+
+To use the middleware, please consider the following:
+
+1) For Rails we could add a configuration in config/application.rb
+
+```ruby
+  config.middleware.use RackPhpProxy, {ssl_verify_none: true}
+```
+
+2) For Sinatra or any Rack-based application:
+
+```ruby
+class MyAwesomeSinatra < Sinatra::Base
+   use  RackPhpProxy, {ssl_verify_none: true}
+end
+```
+
+This will allow to run the other requests through the application and only proxy the requests that match the condition from the middleware.
+
+See tests for more examples.
+
+WARNING
+-------
+
+Doesn't work with fakeweb/webmock. Both libraries monkey-patch net/http code.
+
+Todos
+-----
+
+-	Make the docs up to date with the current use case for this code: everything except streaming which involved a rather ugly monkey patch and only worked in 1.8, but does not work now.
