Advantages of Enterprise Gateway over Traditional Third-Party Proxy Servers
An Enterprise Gateway configuration offers a number of advantages over traditional third-party proxy servers:
*Enterprise Gateway uses persistent connections. These connections eliminate the huge overhead of establishing SSL connections, while providing all the benefits of encryption.
*With Enterprise Gateway, you can configure your inner firewall to deny all inbound connections, isolating the Internal Server from the DMZ.
*Enterprise Gateway requires no changes to the external client.
*Enterprise Gateway rules can be defined to filter client requests.
*An Integration Server acting as an Enterprise Gateway Server can handle both HTTP and HTTPS requests. Typically, third-party proxy servers can handle only one or the other.
