Edit HAProxy pool
Name size="16" maxlength="16">
Status
Cookie size="64">
This value will be checked in incoming requests, and the first operational pool possessing the same value will be selected. In return, in cookie insertion or rewrite modes, this value will be assigned to the cookie sent to the client. There is nothing wrong in having several servers sharing the same cookie value, and it is in fact somewhat common between normal and backup servers. See also the "cookie" keyword in backend section.
