The following are the new features in Oracle Traffic Director 18.104.22.168.0:
This version of Oracle Traffic Director supports the WebSocket protocol. This feature enables Oracle Traffic Director to load balance applications built with WebSocket support.
The previous version of Oracle Traffic Director enabled administrators to configure routing rules to route incoming HTTP/S traffic based on either HTTP/S headers or request URI/query information. Oracle Traffic Director now enables administrators to configure rules to route requests based on content in the body of a request.
Support for LDAP/T3 Load Balancing
Oracle Traffic Director now supports basic LDAP/T3 load balancing at layer 7, where requests are handled as generic TCP connections for traffic tunneling.
Web Logic Server keep-alive synchronization
To improve performance, HTTP keep-alive connections are maintained between Oracle Traffic Director and the origin servers. However, if an origin server closes a connection while Oracle Traffic Director has started sending a request to the server through the connection, it could result in a 503 server error. To prevent this, the connections should always be closed by Oracle Traffic Director, and not by the origin server. Oracle Traffic Director now takes advantage of Web Logic Server-specific HTTP/S headers, whereby Oracle Traffic Director obtains Web Logic Server's keep-alive timeout value and uses it to adjust its own timeout value. This feature is called Keep-Alive Timeout Synchronization.
Non-root high availability
Oracle Traffic Director now supports non-
root high-availability. For more information, see Chapter 14, "Configuring Oracle Traffic Director for High Availability."
Least response time algorithm
Oracle Traffic Director introduces a new load-balancing method called least response time. This method enables Oracle Traffic Director to generate more load on those origin servers that are responding faster than others.
Condition builder enables you to easily build conditions using an interactive GUI. Condition builder is available for use when configuring routes, caching rules, compression rules and request limits.
Web Application Firewalls
Oracle Traffic Director now supports web application firewalls. You can create web application firewalls that enable you to apply a set of rules to HTTP requests, for identifying and blocking attacks. For more information, see Section 11.7, "Managing Web Application Firewalls."
For information about how web application firewall rules are used for preventing attacks, and for some examples and use cases, see Appendix B, "Web Application Firewall Examples and Use Cases."
Oracle Traffic Director on Solaris 11.1
Oracle Traffic Director can now be installed on Solaris 11.1 on Exalogic and Oracle SuperCluster.
