Arduino and the web

Hi, I am trying to use arduino and the ethernet shield to connect to the web.
However, if I try to make a request, it works in the first time , but then for the next attempt, it won't work.
I guess I am getting blocked or my access is denied.
I am using mac Dns connection instead of ip .
Any ideas?

this is the message i get

That appears to be a router attempting to redirect your request to the local proxy server (squid). It will cache the page, and if you request it again within a specific time period, it will send you to the cached page on the proxy server.
