I've got the following problem with nginx working with IIS, when enabled the client certificate in the SSL Settings solicitation IIS, it performs two SSL handshake, a first without requesting the certificate after this first handshake is done another handshake requesting the certificate. The operation is done as explained in this link: http://blogs.technet…ertificate-authentication.aspx
When access the application through the nginx reverse is done only one handshake already requesting the certificate, resulting in no operation of the application.
