<p class="MsoNormal"><span style="color:#1F497D">I need to provide access to a API service exposed on the internet to my clients. That API uses a certificate signed by a private CA.<o:p></o:p></span></p>

unless explicitly configured. )<o:p></o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D">To avoid that I tried ignoring the ssl validation error with sslproxy_cert_error directive and then splicing the connection. But its not working out.<o:p></o:p></span></p>
