How to detect TCP Client disconnect in Ruby

Assuming you want to detect if a server is not responding in a timely manner, then you can use the timeout function of Net::HTTP.

http = Net::HTTP.new(uri.host, uri.port)
http.open_timeout = http.read_timeout = 1.0 #seconds

Then when you perform a Get or other Net::HTTP action, you can rescue Exception, or specifically the timeout exception, to do something on timeout.
