Hi all, I am new on this stuff so I apologize if the question is too silly. I am using SQUID 2.6 Stable 21 running in a Red Hat Linux server. The issue that I can not solve is that when I received an http get, from a client the packet arrives to the squid with the Proxy-Authorization header. Following is a tcpdump of an httpget received by the squid. Proxy-Authorization: Basic NTMzMDAwN zg3NTMwMTc2Mzo=. Credentials: 5330008986641731 I need to forward this header in order to be used by the next-hop-proxy-server to authenticate the user. But, when the request is sent to the next-hop-proxy-server the packet is sent without this specific header. I have defined a testing ACL acl redir_acl2 dstdomain .google.com For this ACL, I have tried to configure the header_access options unsuccessfully. header_access Proxy-Authorization allow redir_acl2 Can you tell me what can I do to forward this specific header? Thanks a lot. K -- View this message in context: http://www.nabble.com/Proxy-header-forwarding-tp24722476p24722476.html Sent from the Squid - Users mailing list archive at Nabble.com.
