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.
