Squid users, I am having a problem accessing/using certain Java enabled websites through my squid proxy. I am using squid-2.6.STABLE6-0.10 on a Suse machine (yes, I know this is an ancient release...). This release has been serving us very well and I am a bit reluctant to upgrade. However, I am willing to investigate that as an option. The proxy uses ntlm_auth to authenticate users against our ADS servers. This works fine...except for some Java sites. For some sites, the Java client seems unable to authenticate, but for this site, that does not seem to be the case. This site in particular is strange for me. It uses a Java applet to upload photos in order to create a gallery from them. It works partially, until the client actually wants to perform the upload, when I get a "software connection abort" from the client. I have a wireshark/tcpdump file of the transaction, taken on the proxy. I think the POST request from the client fails because it does not identify the HTTP protocol version. I have specified the following option in the squid.conf file: "relaxed_header_parser on" in order to get around this issue, but unfortunately this has no effect. My squid.conf is as follows: http_port 10.254.202.14:3128 hierarchy_stoplist cgi-bin ? acl QUERY urlpath_regex cgi-bin \? cache deny QUERY acl apache rep_header Server ^Apache broken_vary_encoding allow apache maximum_object_size_in_memory 15 KB access_log /var/log/squid/access.log squid emulate_httpd_log on url_rewrite_program /usr/local/bin/squidGuard -c /usr/local/squidGuard/squidGuard.conf url_rewrite_children 10 auth_param ntlm program /usr/bin/ntlm_auth --helper-protocol=squid-2.5-ntlmssp auth_param ntlm children 40 auth_param ntlm keep_alive off auth_param basic program /usr/bin/ntlm_auth --helper-protocol=squid-2.5-basic auth_param basic children 5 auth_param basic realm Squid proxy-caching web server at Gemeente Nederweert auth_param basic credentialsttl 2 hours auth_param basic casesensitive off refresh_pattern ^ftp: 1440 20% 10080 refresh_pattern ^gopher: 1440 0% 1440 refresh_pattern . 0 20% 4320 negative_ttl 15 minutes acl all src 0.0.0.0/0.0.0.0 acl manager proto cache_object acl localhost src 127.0.0.1/255.255.255.255 10.254.202.14/255.255.255.255 acl to_localhost dst 127.0.0.0/8 acl SSL_ports port 443 acl Safe_ports port 80 # http acl Safe_ports port 21 # ftp acl Safe_ports port 443 # https acl Safe_ports port 70 # gopher acl Safe_ports port 210 # wais acl Safe_ports port 1025-65535 # unregistered ports acl Safe_ports port 280 # http-mgmt acl Safe_ports port 488 # gss-http acl Safe_ports port 591 # filemaker acl Safe_ports port 777 # multiling http acl CONNECT method CONNECT http_access allow manager localhost http_access deny manager http_access deny !Safe_ports http_access deny CONNECT !SSL_ports http_access deny to_localhost acl purge method PURGE http_access allow purge acl CKBONLINE dstdomain .ckb-online.nl always_direct allow CKBONLINE acl TPG dstdomain .securepostplaza.tntpost.nl always_direct allow TPG acl Java browser Java/1.4 Java/1.5 Java/1.6 Java/1.6.0_12 jupload/0.87 http_access allow Java acl POST method POST # temporary, to get around post problem http_access allow POST acl AuthorizedUsers proxy_auth REQUIRED http_access allow all AuthorizedUsers http_access deny all http_reply_access allow all icp_access allow all error_directory /usr/share/squid/errors/Dutch snmp_port 0 strip_query_terms off coredump_dir /var/cache/squid ie_refresh on relaxed_header_parser on I hope that someone who is more experienced with squid can help me, because I have exhausted my own ideas.
