You aren't being stung by some institutional proxy server or something like that (sorry I don't know much about networks) are you? I imagine ad.doubleclick.net gets a lot of hits. Jon -----Original Message----- From: Nigel Gilbert [mailto:n.gilbert@soc.surrey.ac.uk] Sent: 18 June 2003 19:25 To: ruby-talk ML Subject: TCP/IP protocol and Net::HTTP For almost all web sites, such as www.ruby-lang.org, the code Net::HTTP.get_print 'www.ruby-lang.org', '/' works without a problem, returning the home page. However, 'ad.doubleclick.net' is an exception. The code; Net::HTTP.get_print 'ad.doubleclick.net', '/' times out. If you access this site in a web browser, there is no problem getting the home page from doubleclick; it arrives almost immediately. By watching the ethernet traffic, it seems that doubleclick replies from a different IP address than the address corresponding to the domain name, but ruby keeps listening to responses from the domain address (note this is _not_ a 302 redirect; it is all happening at a much lower level). Eventually, there is a timeout error from /usr/local/lib/ruby/1.6/net/protocol.rb:449:in `initialize'. Is this possible within the TCP/IP protocol? Is this something that has been dealt with in a latter release (I am still using ruby 1.6.8). Is there some workaround?
