[squid-users] odd problem with a web site

For a long time we have had a problem with the web site:

http://www.datasheetarchive.com/

We can navigate the site ok but when trying to download a PDF from the
site we get back:

"Could not execute query : Please contact administrator_at_datasheetarchive.com."

I can reproduce the problem by searching for a component
(e.g. 2n3055), clicking on the PDF symbol and then clicking on the
thumbnail. At this point I get the above quoted message. This is the
URL my browser is trying to retrieve:

http://www.datasheetarchive.com/pdf-datasheets/Datasheets-115/DSAP002069.pdf

If I just use that URL then I get the error too.

For a long time I thought this was a problem with the site, I
contacted the site admin, he was nice but nothing was resolved. Just
recently I have noticed that if I point my browser at our parent proxy
in the DMZ running squid 2.7stable6 then the PDF will download fine
but if I use one of our internal proxies that use the parent in the
DMZ then I get the error I quoted above.

In summary:

browser -> DMZ squid proxy (works)

browser -> internal squid proxy -> DMZ squid proxy (fails)

all proxies are running squid 2.7stable6
