Hi Eliezer, thanks for your advise and response. I will be more carefull next time, this is my first time at a forum like this. I have my doubt to be a network issue, due that the proxy is behind a fisical gateway, and I do not have control over it, it is another work mate, and he says everything is correct on his side. The thind is that if I use the proxy to go out to internet via another modem, not the fisical gateway, the client can go out to www.correo-gto.com.mx with out any problem, and when I conect it, the way that has to be, is when I have the problem. I want to get into the real problem, and see if the server has something wrong. On the other side, I have installed a new serever with squid 3.1, on the same level as the old proxy, the one with the problem, the new proxy works fine, and the client can go in to the page www.correo-gto.com.mx. I follor your sugest to try wget and here are the results: (1) to the web page that I have the problem, it gaves me time out: # wget http://www.correo-gto.com.mx/internacional/index.1.html --2012-12-05 16:38:16-- http://www.correo-gto.com.mx/internacional/index.1.html Resolving www.correo-gto.com.mx... 184.154.122.58 Connecting to www.correo-gto.com.mx|184.154.122.58|:80... connected.
