I would like to use Ruby's OpenURI to check whether the URL can be properly accessed. So I would like to check its response code (4xx or 5xx means error, etc.) Is it possible to find that?

HTTP response status codes indicate whether a specific HTTP request has been successfully completed. Responses are grouped in five classes: Informational responses ( 100 – 199 ) Successful responses ( 200 – 299 ) Redirection messages ( 300 – 399 )
The HTTP 204 No Content success status response code indicates that a request has succeeded, but that the client doesn't need to navigate away from its current page. This might be used, for example, when implementing "save and continue editing" functionality for a wiki site.
The HTTP 201 Created success status response code indicates that the request has succeeded and has led to the creation of a resource.
HTTP response status codes (or simply status codes) are three-digit codes issued by a server in response to a browser-side request from a client. These status codes serve as a means of quick and concise communication on how the server worked on and responded to the client's request.
You can use the status method to return an array that contains the status code and message.
require "open-uri"
open("http://www.example.org") do |f|
puts f.base_uri #=> http://www.example.org
puts f.status #=> ["200", "OK"]
end
