  # == An HTTP client API for Ruby.
  #
  # Net::HTTP provides a rich library which can be used to build HTTP
  # user-agents.  For more details about HTTP see
  # [RFC2616](http://www.ietf.org/rfc/rfc2616.txt).
  #
  # Net::HTTP is designed to work closely with URI.  URI::HTTP#host,
  # URI::HTTP#port and URI::HTTP#request_uri are designed to work with
  # Net::HTTP.
  #
  # If you are only performing a few GET requests you should try OpenURI.
  #
  # == Simple Examples
  #
  # All examples assume you have loaded Net::HTTP with:
  #
  #   require 'net/http'
  #
  # This will also require 'uri' so you don't need to require it separately.
  #
  # The Net::HTTP methods in the following section do not persist
  # connections.  They are not recommended if you are performing many HTTP
  # requests.
  #
  # === GET
  #
  #   Net::HTTP.get('example.com', '/index.html') # => String
  #
  # === GET by URI
  #
  #   uri = URI('http://example.com/index.html?count=10')
  #   Net::HTTP.get(uri) # => String
  #
  # === GET with Dynamic Parameters
  #
  #   uri = URI('http://example.com/index.html')
  #   params = { :limit => 10, :page => 3 }
  #   uri.query = URI.encode_www_form(params)
  #
  #   res = Net::HTTP.get_response(uri)
  #   puts res.body if res.is_a?(Net::HTTPSuccess)
  #
  # === POST
  #
  #   uri = URI('http://www.example.com/search.cgi')
  #   res = Net::HTTP.post_form(uri, 'q' => 'ruby', 'max' => '50')
  #   puts res.body
  #
  # === POST with Multiple Values
  #
  #   uri = URI('http://www.example.com/search.cgi')
  #   res = Net::HTTP.post_form(uri, 'q' => ['ruby', 'perl'], 'max' => '50')
  #   puts res.body
  #
  # == How to use Net::HTTP
  #
  # The following example code can be used as the basis of an HTTP user-agent
  # which can perform a variety of request types using persistent
  # connections.
  #
  #   uri = URI('http://example.com/some_path?query=string')
  #
  #   Net::HTTP.start(uri.host, uri.port) do |http|
  #     request = Net::HTTP::Get.new uri
  #
  #     response = http.request request # Net::HTTPResponse object
  #   end
  #
  # Net::HTTP::start immediately creates a connection to an HTTP server which
  # is kept open for the duration of the block.  The connection will remain
  # open for multiple requests in the block if the server indicates it
  # supports persistent connections.
  #
  # If you wish to re-use a connection across multiple HTTP requests without
  # automatically closing it you can use ::new and then call #start and
  # #finish manually.
  #
  # The request types Net::HTTP supports are listed below in the section "HTTP
  # Request Classes".
  #
  # For all the Net::HTTP request objects and shortcut request methods you may
  # supply either a String for the request path or a URI from which Net::HTTP
  # will extract the request path.
  #
  # === Response Data
  #
  #   uri = URI('http://example.com/index.html')
  #   res = Net::HTTP.get_response(uri)
  #
  #   # Headers
  #   res['Set-Cookie']            # => String
  #   res.get_fields('set-cookie') # => Array
  #   res.to_hash['set-cookie']    # => Array
  #   puts "Headers: #{res.to_hash.inspect}"
  #
  #   # Status
  #   puts res.code       # => '200'
  #   puts res.message    # => 'OK'
  #   puts res.class.name # => 'HTTPOK'
  #
  #   # Body
  #   puts res.body if res.response_body_permitted?
  #
  # === Following Redirection
  #
  # Each Net::HTTPResponse object belongs to a class for its response code.
  #
  # For example, all 2XX responses are instances of a Net::HTTPSuccess
  # subclass, a 3XX response is an instance of a Net::HTTPRedirection
  # subclass and a 200 response is an instance of the Net::HTTPOK class.  For
  # details of response classes, see the section "HTTP Response Classes"
  # below.
  #
  # Using a case statement you can handle various types of responses properly:
  #
  #   def fetch(uri_str, limit = 10)
  #     # You should choose a better exception.
  #     raise ArgumentError, 'too many HTTP redirects' if limit == 0
  #
  #     response = Net::HTTP.get_response(URI(uri_str))
  #
  #     case response
  #     when Net::HTTPSuccess then
  #       response
  #     when Net::HTTPRedirection then
  #       location = response['location']
  #       warn "redirected to #{location}"
  #       fetch(location, limit - 1)
  #     else
  #       response.value
  #     end
  #   end
  #
  #   print fetch('http://www.ruby-lang.org')
  #
  # === POST
  #
  # A POST can be made using the Net::HTTP::Post request class.  This example
  # creates a URL encoded POST body:
  #
  #   uri = URI('http://www.example.com/todo.cgi')
  #   req = Net::HTTP::Post.new(uri)
  #   req.set_form_data('from' => '2005-01-01', 'to' => '2005-03-31')
  #
  #   res = Net::HTTP.start(uri.hostname, uri.port) do |http|
  #     http.request(req)
  #   end
  #
  #   case res
  #   when Net::HTTPSuccess, Net::HTTPRedirection
  #     # OK
  #   else
  #     res.value
  #   end
  #
  # To send multipart/form-data use Net::HTTPHeader#set_form:
  #
  #   req = Net::HTTP::Post.new(uri)
  #   req.set_form([['upload', File.open('foo.bar')]], 'multipart/form-data')
  #
  # Other requests that can contain a body such as PUT can be created in the
  # same way using the corresponding request class (Net::HTTP::Put).
  #
  # === Setting Headers
  #
  # The following example performs a conditional GET using the
  # If-Modified-Since header.  If the files has not been modified since the
  # time in the header a Not Modified response will be returned.  See RFC 2616
  # section 9.3 for further details.
  #
  #   uri = URI('http://example.com/cached_response')
  #   file = File.stat 'cached_response'
  #
  #   req = Net::HTTP::Get.new(uri)
  #   req['If-Modified-Since'] = file.mtime.rfc2822
  #
  #   res = Net::HTTP.start(uri.hostname, uri.port) {|http|
  #     http.request(req)
  #   }
  #
  #   open 'cached_response', 'w' do |io|
  #     io.write res.body
  #   end if res.is_a?(Net::HTTPSuccess)
  #
  # === Basic Authentication
  #
  # Basic authentication is performed according to
  # [RFC2617](http://www.ietf.org/rfc/rfc2617.txt).
  #
  #   uri = URI('http://example.com/index.html?key=value')
  #
  #   req = Net::HTTP::Get.new(uri)
  #   req.basic_auth 'user', 'pass'
  #
  #   res = Net::HTTP.start(uri.hostname, uri.port) {|http|
  #     http.request(req)
  #   }
  #   puts res.body
  #
  # === Streaming Response Bodies
  #
  # By default Net::HTTP reads an entire response into memory.  If you are
  # handling large files or wish to implement a progress bar you can instead
  # stream the body directly to an IO.
  #
  #   uri = URI('http://example.com/large_file')
  #
  #   Net::HTTP.start(uri.host, uri.port) do |http|
  #     request = Net::HTTP::Get.new uri
  #
  #     http.request request do |response|
  #       open 'large_file', 'w' do |io|
  #         response.read_body do |chunk|
  #           io.write chunk
  #         end
  #       end
  #     end
  #   end
  #
  # === HTTPS
  #
  # HTTPS is enabled for an HTTP connection by Net::HTTP#use_ssl=.
  #
  #   uri = URI('https://secure.example.com/some_path?query=string')
  #
  #   Net::HTTP.start(uri.host, uri.port, :use_ssl => true) do |http|
  #     request = Net::HTTP::Get.new uri
  #     response = http.request request # Net::HTTPResponse object
  #   end
  #
  # Or if you simply want to make a GET request, you may pass in an URI
  # object that has an HTTPS URL. Net::HTTP automatically turns on TLS
  # verification if the URI object has a 'https' URI scheme.
  #
  #   uri = URI('https://example.com/')
  #   Net::HTTP.get(uri) # => String
  #
  # In previous versions of Ruby you would need to require 'net/https' to use
  # HTTPS. This is no longer true.
  #
  # === Proxies
  #
  # Net::HTTP will automatically create a proxy from the +http_proxy+
  # environment variable if it is present.  To disable use of +http_proxy+,
  # pass +nil+ for the proxy address.
  #
  # You may also create a custom proxy:
  #
  #   proxy_addr = 'your.proxy.host'
  #   proxy_port = 8080
  #
  #   Net::HTTP.new('example.com', nil, proxy_addr, proxy_port).start { |http|
  #     # always proxy via your.proxy.addr:8080
  #   }
  #
  # See Net::HTTP.new for further details and examples such as proxies that
  # require a username and password.
  #
  # === Compression
  #
  # Net::HTTP automatically adds Accept-Encoding for compression of response
  # bodies and automatically decompresses gzip and deflate responses unless a
  # Range header was sent.
  #
  # Compression can be disabled through the Accept-Encoding: identity header.
  #
  # == HTTP Request Classes

  #
  # * Net::HTTPRequest
  #   * Net::HTTP::Get
  #   * Net::HTTP::Head

  #   * Net::HTTP::Patch
  #   * Net::HTTP::Put

    #                           not given, a random boundary will be used.
    #              :charset :: The charset of the form submission. All
    #                          field names and values of non-file fields
    #                          should be encoded with this charset.
    #
    # Each item of params should respond to +each+ and yield 2-3 arguments,
    # or an array of 2-3 elements. The arguments yielded should be:
    #  * The name of the field.
    #  * The value of the field, it should be a String or a File or IO-like.
    #  * An options hash, supporting the following options, only
    #    used for file uploads:
    #    :filename :: The name of the file to use.
    #    :content_type :: The content type of the uploaded file.
    #
    # Each item is a file field or a normal field.
    # If +value+ is a File object or the +opt+ hash has a :filename key,
    # the item is treated as a file field.
    #
    # If Transfer-Encoding is set as chunked, this sends the request using
    # chunked encoding. Because chunked encoding is HTTP/1.1 feature,
    # you should confirm that the server supports HTTP/1.1 before using
    # chunked encoding.
    #
    # Example:
    #    req.set_form([["q", "ruby"], ["lang", "en"]])
    #
    #    req.set_form({"f"=>File.open('/path/to/filename')},
    #                 "multipart/form-data",
    #                 charset: "UTF-8",
