Cisco Cisco Web Security Appliance S170

AsyncOS now dynamically adjusts the size of the send buffer for the client-side socket. The option to 
configure the size of this buffer using the MISCELLANEOUS option of the CLI advancedproxyconfig 
command still appears in the CLI, but it's functionality is disabled. Changes made to the buffer size using 
advancedproxyconfig do not take affect.
