Hi Amos and all,

I forgot to mention that I tried loading the page with firefox,
chromium and IE and got the same results with all of them. And all of
them are able to load the page fine when using a direct connection to
the internet (without proxy).

Even so, I see that my first message wasn't somehow displayed properly
and might not be clear enough. Where it says 'But no sight of a ''"e
request.', I meant to say: 'But no sight of a
http://ad.doubleclick.net/adj/site011.opus/home request', meaning that
there is a GET request for the first url but not for the second (as
seen when not using squid but a direct connection to the internet).

I have taken traces of the HTTP traffic with tcpdump, which I show
below. The first one is using squid 2.7, which fails to load the ad
and the second with the direct connection to the internet, which works
flawlessly. As can be seen, when using squid, there is no data in the
reply from the server, whereas there is some in the reply to the same
request when using the direct connection, could the 'not requesting
second url' error be due to this ??
