Chapter 7 Configuring Stickiness
Configuring Sticky Groups
Type The method to be used when establishing sticky connections:
• HTTP Content—The ACE sticks client connections to the same real server based on a string
in the data portion of the HTTP packet. See Table 7-2 for additional configuration options.
• HTTP Cookie—Indicates that the ACE appliance is either to learn a cookie from the HTTP
header of a client request or to insert a cookie in the Set-Cookie header of the response from
the server to the client, and then use the learned cookie to provide stickiness between the client
and server for the duration of the transaction.
• HTTP Header—Indicates that the ACE appliance is to stick client connections to the same real
server based on HTTP headers.
• IP Netmask—Indicates that the ACE appliance is to stick a client to the same server for
multiple subsequent connections as needed to complete a transaction using the client source
IP address, the destination IP address, or both based on their IP netmask. You can optionally
configure an IPv6 prefix length with this sticky type.
Note If an organization uses a megaproxy to load balance client requests across multiple proxy
servers when a client connects to the Internet, the source IP address is no longer a reliable
indicator of the true source of the request. In this situation, you can use cookies or another
sticky method to ensure session persistence.
• IPv6 Prefix—Indicates that the ACE appliance is to stick a client to the same server for
multiple subsequent connections as needed to complete a transaction using the client source
IP address, the destination IP address, or both based on their IPv6 prefix. You can optionally
configure an IPv4 netmask with this sticky type.
• Layer 4 Payload—The ACE sticks client connections to the same real server based on a string
in the payload portion of the Layer 4 protocol packet. See Table 7-6 for additional
configuration options.
• RADIUS—The ACE sticks client connections to the same real server based on a RADIUS
attribute. See Table 7-7 for additional configuration options.
• RTSP Header—The ACE sticks client connections to the same real server based on the RTSP
Session header field. See Table 7-8 for additional configuration options.
• SIP Header—The ACE sticks client connections to the same real server based on the SIP
Call-ID header field.
• SSL—The ACE sticks client connections to the same real server based on the SSL session ID.
Note This option is not available with the ACE NPE software version (see the “Information
About the ACE No Payload Encryption Software Version” section on page 1-2).
Cookie Name This option appears for sticky type HTTP Cookie.
Enter a unique identifier for the cookie. Valid entries are unquoted text strings with no spaces and
a maximum of 64 alphanumeric characters.
