Example 4: Using Rewrite Cookie Mode
n
Rewrite server cookie with the encrypted real server IP address:
In cookie rewrite mode, if the cookie length parameter is configured to be eight bytes, the
switch will rewrite the placeholder cookie value with the encrypted real server IP address.
If the server is configured to include a placeholder cookie, such as follows:
Set-Cookie: sid=alteonpersistence;
then the Web switch will rewrite the first eight bytes of the cookie to include the server’s
encrypted IP address:
Set-Cookie: sid=cdb20f04rsistence;
All subsequent traffic from a specific client with this cookie will be directed to the same
real server.
n
Rewrite server cookie with the encrypted real server IP address and virtual server IP
address:
If the cookie length is configured to be 16 bytes, the switch will rewrite the cookie value
with the encrypted real server IP address and virtual server IP address.
If the server is configured to include a placeholder cookie, as follows:
Set-Cookie: sid=alteonwebcookies;
then the Web switch will rewrite the first 16 bytes of the cookie to include the encrypted
real server IP address and virtual server IP address:
Set-Cookie: sid=cdb20f04cdb20f0a;
All subsequent traffic from a specific client to the particular virtual server IP address with
this cookie will be directed to the same real server.
