close() click to toggle source

Close any resource used by the response

    # File lib/thin/response.rb, line 76
76:     def close
77:       @body.close if @body.respond_to?(:close)
78:     end

each() click to toggle source

Yields each chunk of the response. To control the size of each chunk define your own each method on body.

    # File lib/thin/response.rb, line 83
83:     def each
84:       yield head
85:       if @body.is_a?(String)
86:         yield @body
87:       else
88:         @body.each { |chunk| yield chunk }
89:       end
90:     end

head() click to toggle source

Top header of the response, containing the status code and response headers.

    # File lib/thin/response.rb, line 39
39:     def head
40:       "HTTP/1.1 #{@status} #{HTTP_STATUS_CODES[@status.to_i]}\r\n#{headers_output}\r\n"
41:     end

headers=(key_value_pairs) click to toggle source

Ruby 1.8 implementation. Respects Rack specs.

See rack.rubyforge.org/doc/files/SPEC.html

    # File lib/thin/response.rb, line 49
49:       def headers=(key_value_pairs)
50:         key_value_pairs.each do |k, vs|
51:           vs.each { |v| @headers[k] = v.chomp } if vs
52:         end if key_value_pairs
53:       end

headers=(key_value_pairs) click to toggle source

Ruby 1.9 doesn’t have a String#each anymore. Rack spec doesn’t take care of that yet, for now we just use each but fallback to each_line on strings. I wish we could remove that condition. To be reviewed when a new Rack spec comes out.

    # File lib/thin/response.rb, line 62
62:       def headers=(key_value_pairs)
63:         key_value_pairs.each do |k, vs|
64:           next unless vs
65:           if vs.is_a?(String)
66:             vs.each_line { |v| @headers[k] = v.chomp }
67:           else
68:             vs.each { |v| @headers[k] = v.chomp }
69:           end
70:         end if key_value_pairs
71:       end

headers_output() click to toggle source

String representation of the headers to be sent in the response.

    # File lib/thin/response.rb, line 29
29:     def headers_output
30:       # Set default headers
31:       @headers[CONNECTION] = persistent? ? KEEP_ALIVE : CLOSE
32:       @headers[SERVER]     = Thin::SERVER
33: 
34:       @headers.to_s
35:     end

persistent!() click to toggle source

Tell the client the connection should stay open

    # File lib/thin/response.rb, line 93
93:     def persistent!
94:       @persistent = true
95:     end

persistent?() click to toggle source

Persistent connection must be requested as keep-alive from the server and have a Content-Length, or the response status must require that the connection remain open.

     # File lib/thin/response.rb, line 100
100:     def persistent?
101:       (@persistent && @headers.has_key?(CONTENT_LENGTH)) || PERSISTENT_STATUSES.include?(@status)
102:     end
