+### Disabling SNI\r
+\r
+You may run into SNI alerts (Server Name Indication).  These will manifest as failures to clone or push to your Gitblit instance.\r

+#### Java-based Clients\r
+\r
+When using Java 7-based clients, SNI is enabled by default.  You can disable SNI by specifying the JVM system parameter `-Djsse.enableSNIExtension=false` when your Java-based client launches.\r
+\r
+For Eclipse, you can append `-Djsse.enableSNIExtension=false` to your *eclipse.ini* file.\r
