Hi Amos, thanks for answering. Im using Squid 3.5.12 I tried using the line: sslproxy_client_certificate /home/ubuntu/Documents/cert.pem The pem was generated from .pfx using, openssl pkcs12 -in cert.pfx -out cert.pem -nodes So it should contain the private key. But my server still asking me for the certificate.^ Any ideas? -- View this message in context: http://squid-web-proxy-cache.1019090.n4.nabble.com/Using-client-certificate-for-all-connection-tp4681942p4682016.html Sent from the Squid - Users mailing list archive at Nabble.com. _______________________________________________ squid-users mailing list squid-users@xxxxxxxxxxxxxxxxxxxxx http://lists.squid-cache.org/listinfo/squid-users
