when my problem is using multithreading to get some documents from www  
server through net::http library. The code is as follows

Net::HTTP.start(url.host) do |http|  
req = Net::HTTP::Get.new(url.path, {“User-Agent” =\>  
“Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; SV1; .NET CLR  
1.1.4322; InfoPath.1)”})  
response = http.request(req)  
http.finish()  
case response  
when Net::HTTPSuccess  
then return response.body  
else  
puts “Response Not Success”  
return “”  
end  
end

I always receive errors as follows:
