Server Load Balancing
>> HTTP Content Rule 10# group
Current real server group: 1
Enter new real server group [1-1024]: 10
6. Because a session cookie does not exist in the first request of an HTTP session, a default server
group is needed to assign cookies to a None cookie HTTP request. Create a server group
containing designated servers for example servers 1 through 10, and associate it to the HTTP
virtual service as the fallback group.

Using this example, the following results:
— Request 1 comes in with no cookie. It is load balanced between servers in Group 15 (Real
Servers 1 through 10) to receive a response and a cookie assigned.
— Request 2 comes in with a "Gold" cookie; it is load balanced between servers in Group 10
(Real Servers 1 through 4).
— Request 3 comes in with a "Silver" cookie; it is load balanced between servers in Group 11
(Real Servers 5 through 8).
— Request 4 comes in with a "Bronze" cookie; it is load balanced between servers in Group 12
(Real Servers 9 through 10).
