See bug 1242 http://www.squid-cache.org/bugs/show_bug.cgi?id=1242 The issue is that with 2.5S8 (or well patched 2.5S7) squid has become less tolerant of illegal behaviour from web servers in the headers they serve before the contents of the web page. If you fetch that page by hand (eg. with wget -S) you can see the HTTP headers 1 HTTP/1.0 200 OK 2 Server: Microsoft-IIS/3.0 3 Date: Fri, 18 Feb 2005 19:54:50 GMT 4 HTTP/1.1 200 OK 5 content-type: text/html 6 content-length: 2617 7 Connection: Keep-Alive which is difficult to make sense of if you actually try to understand it; is the answer HTTP/1.1 or HTTP/1.0?
