[ruby-core:38719] [Ruby 1.9 - Bug #4964] open-uri failed to handle multiple "Set-Cookie" headers

Issue #4964 has been updated by Akira Tanaka.

Target version changed from 1.9.3 to 1.9.x

I think we can fix the problem without incompatibility.
(new method to return array of field bodies for a field name.)

It needs new feature, though.

Bug #4964: open-uri failed to handle multiple "Set-Cookie" headers

== Problem
open-uri handle multiple "Set-Cookie" headers in a wrong way. Given a header from http server like:

       Set-Cookie: name1=value1; blabla
       Set-Cookie: name2=value2; blabla


open-uri will pack it into meta info of result like:

       Set-Cookie: name1=value; blabla, name2=value2; blabla

The problem is that line 332 of open-uri.rb
        resp.each {|name,value| buf.io.meta_add_field name, value }

In turn will call invoke code in net/http.rb to join headers with ",".

== ruby -v:
ruby 1.9.2p174 (2011-01-28 revision 30696) [i686-linux]

== code:
 require 'open-uri'
 begin
   open "http://douban.fm", :redirect => false
 rescue OpenURI::HTTPRedirect => redirect
   redirect.io.meta['set-cookie']
 end




=end
