## New features

Following are new features in this release.

### Server Name Indication (SNI) support

Edge supports the use of Server Name Indication southbound (from message processor to target
endpoints) in on-premises deployments.

**Java 1.7** is required.

With SNI, which is an extension of TLS/SSL, multiple HTTPS targets can be served off the same
IP address and port without requiring all those targets to use the same certificate.

No Edge-specific configuration is required. If your environment is configured for southbound
SNI (Edge cloud is by default), Edge supports it.

Edge automatically extracts the hostname from the request URL and adds it to
the SSL handshake request. For example, if the target host is https://example.com/request/path, then Edge
adds the server_name extension as
shown below:

For more information on SNI, see [http://en.wikipedia.org/wiki/Server_Name_Indication](https://en.wikipedia.org/wiki/Server_Name_Indication).

#### Disabling SNI

Apigee enabled SNI by default. You can disable this feature by setting the following property to false in /opt/apigee4/conf/apigee/message-processor/system.properties on the Message Processors:

```
jsse.enableSNIExtension=false
```

You must then restart the Message Processors using the command:

```
/opt/apigee4/bin/apigee-service message-processor restart
```
