The SA8250 can be configured to maintain a session’s state so that
serial requests from a single client are allocated to the same server.
This is called "sticky port" functionality. This command enables or
disables the sticky port function. Sticky functionality is enabled in
either of two modes. "Src-ip" (source IP address) mode identifies
requesting clients by IP address."Cookie" mode entails sending a
cookie to requesting browsers which identifies subsequent
requests as coming from the same client.
Note: This mode must be used to enable sticky ports in
environments in which requests come to the SA8250 through
proxy servers. (All requests coming from a proxy server have that
server’s address as their apparent Source IP address, rather than the
actual address of their origination.) Sticky Cookie mode is
available only to RICH_HTTP services.
