A request/response rewriting HTTP proxy. A Rack app.

A request/response rewriting HTTP proxy. A Rack app.

Subclass Rack::Proxy and provide your rewrite_env and rewrite_response methods.

Example:

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

Example: disable SSL session verification when proxying a server with e.g. self-signed SSL certs

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

    Rack::Proxy.new(ssl_verify_none: true)

See tests for more examples.

WARNING: Doesn't work with fakeweb/webmock. Both libraries monkey-patch net/http code.

TODO: 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.
