title: Does haproxy support OCSP for client certificate validation
body: <p>We are configuring HAProxy to force require Client Certificate Validation. This works well. However, we couldn't find much information about OCSP support specifically for client certificate validation. There are information about Certificate Revocation list and OCSP Stapling (which I believe is for server certificates). 
  So my questions are 
  1. Does HAProxy supports OCSP during client certificate validation? 
  and 
  2. If it is supported, can this be manually configured without requiring the OCSP URL included in the client certificate itself or possibly overriding the url on the server? </p>
