FWIW, you can test the jse.trivago.com request by manually requesting =
(from Safari on OS X): =

It=E2=80=99s just a big JS library for hunting prices down.  I had some =

them to price match that :)

As for the weird connectivity, I know TPG for a long time ran =
transparent proxies without really making it widely known.  I=E2=80=99ve =
seen similar behaviour to that which you describe when my local Squid =
cache get=E2=80=99s it=E2=80=99s panties in a bunch.  =E2=80=9Csquid -k =
restart=E2=80=9D usually does the trick.  However, before rattling =
TPG=E2=80=99s cage, maybe try flushing the browser cache and see if the =
problems persist.

Good luck.
