Rack::Utils Basic information

Problem

Every HTTP statuses code are available in form of symbol in Rails in a slightly more readable form. You may heard few of them like

{% highlight ruby %} :ok :not_modified {% endhighlight %}

We’re interested to use every status to symbol which looks good to me. Following can be found on Rails Console/Documentation via

{% highlight ruby %} Rack::Utils::SYMBOL_TO_STATUS_CODE

=> { :continue=>100, :switching_protocols=>101, :processing=>102, :ok=>200, :created=>201, :accepted=>202, :non_authoritative_information=>203, :no_content=>204, :reset_content=>205, :partial_content=>206, :multi_status=>207, :already_reported=>208, :im_used=>226, :multiple_choices=>300, :moved_permanently=>301, :found=>302, :see_other=>303, :not_modified=>304, :use_proxy=>305, :temporary_redirect=>307, :permanent_redirect=>308, :bad_request=>400, :unauthorized=>401, :payment_required=>402, :forbidden=>403, :not_found=>404, :method_not_allowed=>405, :not_acceptable=>406, :proxy_authentication_required=>407, :request_timeout=>408, :conflict=>409, :gone=>410, :length_required=>411, :precondition_failed=>412, :payload_too_large=>413, :uri_too_long=>414, :unsupported_media_type=>415, :range_not_satisfiable=>416, :expectation_failed=>417, :unprocessable_entity=>422, :locked=>423, :failed_dependency=>424, :upgrade_required=>426, :precondition_required=>428, :too_many_requests=>429, :request_header_fields_too_large=>431, :internal_server_error=>500, :not_implemented=>501, :bad_gateway=>502, :service_unavailable=>503,:gateway_timeout=>504, :http_version_not_supported=>505, :variant_also_negotiates=>506, :insufficient_storage=>507, :loop_detected=>508, :not_extended=>510, :network_authentication_required=>511 }

{% endhighlight %}

Rack::Utils contains a grab-bag of useful methods for writing web applications adopted from all kinds of Ruby libraries. It contains methods like - {% highlight ruby %} .add_cookie_to_header(header, key, value) ⇒ Object .add_remove_cookie_to_header(header, key, value = {}) ⇒ Object {% endhighlight %}

which sound quite handy to play with header cookies and there are lots of more stuff.
