+To enable OCSP Stapling for a domain, `nginx-proxy` looks for a PEM certificate containing the trusted

 #### How SSL Support Works
 
-The default SSL cipher configuration is based on the [Mozilla intermediate profile](https://wiki.mozilla.org/Security/Server_Side_TLS#Intermediate_compatibility_.28default.29) which
-should provide compatibility with clients back to Firefox 1, Chrome 1, IE 7, Opera 5, Safari 1,
-Windows XP IE8, Android 2.3, Java 7.  Note that the DES-based TLS ciphers were removed for security.
-The configuration also enables HSTS, PFS, OCSP stapling and SSL session caches.  Currently TLS 1.0, 1.1 and 1.2
-are supported.  TLS 1.0 is deprecated but its end of life is not until June 30, 2018.  It is being
-included because the following browsers will stop working when it is removed: Chrome < 22, Firefox < 27,
-IE < 11, Safari < 7, iOS < 5, Android Browser < 5.
