Server-Side Multi-Response Cookie Search
Cookie-based persistence requires the switch to search the HTTP response packet from the
server and, if a persistence cookie is found, sets up a persistence connection between the server
and the client. The Alteon switch looks through the first HTTP response from the server. While
this approach works for most servers, some customers with complex server configurations
might send the persistence cookie a few responses later. In order to achieve cookie-based per-
sistence in such cases, Web OS 10.0 allows the network administrator to configure the switch
to look through multiple HTTP responses from the server.
In Web OS 10.0, the network administrator can modify a response counter to a value from 1-
16. The switch will look for the persistence cookie in this number of responses (each of them
can be multi-frame) from the server.
Configuring Server-Side Multi-Response Cookie Search
Configure the server-side multi-response cookie search by using the following command:
>> # /cfg/slb/virt <virtual server>/service <virtual port number>/rcount
Current Cookie search response count:
