I had a similar issue lately (not sure it is similar): I wanted to feed
extra headers when redirected.
I use http-access2 instead of net/http
Here's a sample code that worked for me.

#!/usr/bin/ruby

require 'http-access2'
require 'pp'

target =3D ARGV.shift || "http://localhost/foo.cgi"

clnt =3D HTTPAccess2::Client.new
clnt.debug_dev =3D STDERR

extheaders =3D []

clnt.set_cookie_store("cookie.dat")
clnt.redirect_uri_callback =3D lambda { |res|
  uri =3D res.header['Location'][0]
  if res.header['set-cookie']
    res.header['set-cookie'].each do |cookie|
        puts cookie
        puts uri
        extheaders << ['Cookie', cookie]
        #bug in cookie manager, does not work, the uril for the cookie
misses the first element pof the path
#        clnt.cookie_manager.parse(cookie, URI.parse(uri))
        end
  end
  clnt.save_cookie_store
  pp clnt.cookie_manager
  URI.parse(uri)
}

puts
puts '=3D GET content directly'
puts clnt.get_content(target, nil, extheaders)
puts '=3D GET result object'
result =3D clnt.get(target)
puts '=3D=3D Header object'
p result.header
puts "=3D=3D Content-type"
p result.contenttype
puts '=3D=3D Body object'
p result.body
puts '=3D=3D Content'
print result.content
puts '=3D=3D GET with Block'
clnt.get(target) do |str|
  puts str
end
clnt.save_cookie_store
