New Features¶ ↑

• A middleware_stack plugin has been added for more detailed control over middleware, allowing for the removal of middleware and the insertion of middleware before existing middleware. Example:

  plugin :middleware_stack
  
  # Remove csrf middleware
  middleware_stack.remove{|m, *args| m == Rack::Csrf}
  
  # Insert csrf middleware before logger middleware
  middleware_stack.before{|m, *args| m == Rack::CommonLogger}.
    use(Rack::Csrf, raise: true)
  
  # Insert csrf middleware after logger middleware
  middleware_stack.after{|m, *args| m == Rack::CommonLogger}.
    use(Rack::Csrf, raise: true)
  

Other Improvements¶ ↑

• The head plugin now calls close on the response body if the body responds to close. Previously an existing response body was just ignored.
