Hello to all,  
I am using ‘open-uri’ & ‘pp’ ruby library, to open url and gather some  
data from given web page. But it throws following error

c:/ruby/lib/ruby/1.8/open-uri.rb:278:in `open_http': 500 Internal Server Error ( OpenURI::HTTPError) from c:/ruby/lib/ruby/1.8/open-uri.rb:617:in `buffer\_open’  
from c:/ruby/lib/ruby/1.8/open-uri.rb:164:in `open_loop' from c:/ruby/lib/ruby/1.8/open-uri.rb:162:in `catch’  
from c:/ruby/lib/ruby/1.8/open-uri.rb:162:in `open_loop' from c:/ruby/lib/ruby/1.8/open-uri.rb:132:in `open\_uri’  
from c:/ruby/lib/ruby/1.8/open-uri.rb:519:in `open' from c:/ruby/lib/ruby/1.8/open-uri.rb:30:in `open’  
from openmyurl.rb:4

source code openurl.rb is like-----

require ‘open-uri’  
require ‘pp’

open(‘[http://www.aflatune.com/](http://www.aflatune.com/)’) do |f|

# hash with meta information

pp f.meta

# 

pp "Content-Type: " + f.content\_type  
pp “last modified” + f.last\_modified.to\_s

no = 1

# print the first fifty lines

f.each do |line|  
print “#{no}: #{line}”  
no += 1  
break if no \> 50  
end  
end

can any one give me solution to how to solve this problem?

this works for me:  
open(‘[http://www.aflatune.com/](http://www.aflatune.com/)’, ‘User-Agent’=\>‘ruby’)
