Hi It seems when going through our squid server users aren't able to play the online game at www.runescape.com. After some investigation I see that the game runs on ports 43594 and 43595, so I added these to the squid.conf safe ports. However the following message is shown in the web browser: #################### While trying to process the request: GET /serverlist.ws?plugin=0&lores.x=163&lores.y=50 HTTP/1.0 Accept: image/gif, image/x-xbitmap, image/jpeg, image/pjpeg, application/x-shockwave-flash, application/vnd.ms-excel, application/vnd.ms-powerpoint, application/msword, */* Referer: http://www.runescape.com/detail.ws Accept-Language: en-gb Proxy-Connection: Keep-Alive User-Agent: Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; SV1; .NET CLR 1.1.4322) Host: www.runescape.com Cookie: RSORIGIN=RUNESCAPE; serverlist_order=MLPW; RSCOUNTRY=0; jagextimeout109=1145532184571 The following error was encountered: Invalid Response The HTTP Response message received from the contacted server could not be understood or was otherwise malformed. Please contact the site operator. Your cache administrator may be able to provide you with more details about the exact nature of the problem if needed. #################### I'm not sure where the problem is. So wondered if anyone else has had the same issue and managed to solve it? I'm running squid on a centos 4.3 box with squid version 2.5.STABLE6 which was installed via rpm. Output of squid -v is: Squid Cache: Version 2.5.STABLE6 configure options: --build=i686-redhat-linux-gnu --host=i686-redhat-linux-gnu --target=i386-redhat-linux-gnu --program-prefix= --prefix=/usr --exec-prefix=/usr --bindir=/usr/bin --sbindir=/usr/sbin --sysconfdir=/etc --datadir=/usr/share --includedir=/usr/include --libdir=/usr/lib --libexecdir=/usr/libexec --localstatedir=/var --sharedstatedir=/usr/com --mandir=/usr/share/man --infodir=/usr/share/info --exec_prefix=/usr --bindir=/usr/sbin --libexecdir=/usr/lib/squid --localstatedir=/var --sysconfdir=/etc/squid --enable-poll --enable-snmp --enable-removal-policies=heap,lru --enable-storeio=aufs,coss,diskd,null,ufs --enable-ssl --with-openssl=/usr/kerberos --enable-delay-pools --enable-linux-netfilter --with-pthreads --enable-ntlm-auth-helpers=SMB,winbind --enable-external-acl-helpers=ip_user,ldap_group,unix_group,wbinfo_group,win bind_group --enable-auth=basic,ntlm --with-winbind-auth-challenge --enable-useragent-log --enable-referer-log --disable-dependency-tracking --enable-cachemgr-hostname=localhost --disable-ident-lookups --enable-truncate --enable-underscores --datadir=/usr/share --enable-basic-auth-helpers=LDAP,MSNT,NCSA,PAM,SMB,YP,getpwnam,multi-domain- NTLM,SASL,winbind Thanks Tony -- This message has been scanned for viruses and dangerous content by MailScanner, and is believed to be clean.
