Cisco Content Switching Module Software Version 4.1(1) for the Cisco Catalyst 6500 Series Switch and Cisco 7600 Series Router
New Features
New features of the Cisco® Content Switching Module (CSM) Software Version 4.1(1) for the Cisco Catalyst® 6500 Series Switch and Cisco 7600 Series Router are described in the following sections.
Offset/length sticky—This feature allows an administrator to specify the exact bytes of a cookie to use for session persistence. This capability is particularly useful when working with applications that use dynamic cookies where only a portion of the cookie remains constant during a session. In this case, the administrator can specify the static bytes in the cookie to use for persistence. This feature adds enhanced support for Java 2 Platform, Enterprise Edition (J2EE) based applications such as BEA WebLogic and IBM WebSphere among others.
Insert cookie—This feature provides the CSM with the capability to insert an administrator configurable cookie into the HTTP header of the first packet returning from the server to the client. The cookie can then be used to ensure that subsequent client requests return to the same real server on the back end. This feature is useful in situations where it is desirable to use cookies for persistence but the server is unable to set cookies.
IP header insert—This feature provides the capability to insert information into the IP header, such as the client IP address. This is especially useful in situations where client Network Address Translation (NAT) is used but the original client information is still required by the back-end server for applications such as accounting.
Back-end Secure Sockets Layer (SSL) solution—Together with the SSL module for the Cisco Catalyst 6500 Series switches and Cisco 7600 series routers, the CSM provides a complete solution for intelligent load balancing and end-to-end encryption. Because the CSM and SSL modules are housed in the same chassis, this solution provides the capability to make an intelligent load-balancing decision up to Layer 7 and to ensure that the request continues on to the back-end real server encrypted.
