You need to look at the headers they are sending Squid. See what is
different between the two.

Which release version of Squid?

And are you doing this on a reverse proxy for elpais.com? If you have
squid 3.1+ use the "ignore-cc" option on your accel http_port instead of
all that horrid algorithm overriding.

If you are a separate admin do the whole world a favor and contact them
about fixing their website headers so their content caches appropriately.

That the server produces non-compressed objects with the wrong Vary:
header.
