Configuring Back-End SSL Servers in an SSL Initiation Proxy List
To disable the Nagle algorithm for the TCP connection between the server and the
SSL module, enter:
(config-ssl-proxy-list[ssl_list1])# backend-server 1 tcp server nagle
disable
To reenable the Nagle algorithm for the TCP connection between the server and
the SSL module, enter:
(config-ssl-proxy-list[ssl_list1])# backend-server 1 tcp server nagle
enable
Specifying the TCP Buffering for SSL TCP Connections
If you experience unacceptable latency in your network due to congestion, you
can increase the buffer size that the CSS buffers for a given TCP connection
before shutting down the TCP window to 0. Use the backend-server number tcp
buffer-share command to set the TCP buffering from the client or server on a
given connection. The syntax for this command is:
backend-server number tcp buffer-share rx number1|tx number2
To set the amount of data in bytes that a given connection can buffer from the
client traffic, use the rx number1 keyword and variable. By default, the buffer size
is 32768. The buffer size can range from 16400 to 262144. For example, to set the
value to 65536, enter:
(config-ssl-proxy-list[ssl_list1])# backend-server 1 tcp buffer-share
rx 65536
To reset the buffer size to the default of 32768, enter:
(config-ssl-proxy-list[ssl_list1])# no backend-server 1 tcp
buffer-share rx
To set the amount of data in bytes that a given connection can buffer from the
server to the client, use the tx number2 keyword and variable. By default, the
buffer size is 65536. The buffer size can range from 16400 to 262144. For
example, to set the value to 131072, enter:
(config-ssl-proxy-list[ssl_list1])# backend-server 1 tcp buffer-share
tx 131072
