title: squid proxy to bump two way ssl
body: <p>I am using squid proxy to bump SSL when my client connecting to server which runs on TLS 1.2. Recently a new server which requires two way ssl connection ( with TLS 1.2 ) has been added and my client is given a certificate to communicate with two way ssl server. How can I bump two way ssl connection using squid proxy ?</p>
  <p>Squid config --</p>

  acl step2 at_step SslBump2
  acl step3 at_step SslBump3
