Squid-3.1 is still mostly HTTP/1.0 software and IE has problems using HTTP/1.1 to a 1.0 proxy. You could avoid that by upgrading Squid, perferrably to the current supproted release (3.4.4). I have a client running many IE11 with their default settings behind a Squid-3.4 and not seeing problems. Amos
