Salve ragazzi,

come posso gestire i warning di Net::HTTP? Ad esempio se provo a  
connetermi verso un host il cui web server non è in ascolto o è filtrato  
ottengo:

/usr/lib/ruby/1.8/net/http.rb:562:in `initialize’: Connection refused -  
connect(2) (Errno::ECONNREFUSED)

Come posso gestire l’evento e permettere che lo script vada avanti  
nell’esecuzione?

…  
…  
url = URI.parse(“http://#{target}:#{port}/admin/”)  
req = Net::HTTP::Get.new(url.path)  
res = Net::HTTP.start(url.host, url.port){|http|  
http.request(req)  
}

if (res.code.match(/200/))  
…  
…

Grazie mille,  
Alfonso
