[squid-users] Zero Sized Reply / Invalid response

Hello,

Our Company is using Squid 2.6.STABLE14 on a Slackware 12.0 box. A few
weeks ago we began to have errors accessing some web pages, but not
all, on a supplier web site. If we do not use a proxy server we can
access those web pages; we have tested it with Safari, Camino and
Firefox on Mac OS X, and IE 6 and 7, and Firefox on Windows. On Squid
2.6 we get a Zero Sized Reply error; on a Squid 3.0.STABLE7 test box
(also on Slackware 12.0) we have an Invalid Response Error. If, on
Internet Explorer, we disable the use of HTTP/1.1 on proxy connections
we can access the page using Squid.

The supplier insists that since we can access the pages without Squid,
the problem must be ours. I replied him that it all begin a few weeks
ago, so the problem is theirs.

The URL are these:

http://www.transhotel.com/pls/b2b/pka102.p001?pIdHotel=146334&pIDProducto=1&pIdioma=ESP&pTarifas=2008&pEjercicio=undefined
http://www.transhotel.com/pls/b2b/pka102.p001?pIdHotel=146334&pIDProducto=1&pIdioma=ESP&pTarifas=2008
http://www.transhotel.com/pls/b2b/pka102.p001?pIdHotel=146241&pIDProducto=1&pIdioma=ESP&pTarifas=2008&pEjercicio=undefined

Interestingly if on the last URL we omit the last parameter
(pEjercicio) we can access the page.

These are the errors:

ERROR
