Edit HAProxy server
Name size="16" maxlength="16">
Frontend(s) 0) $tracker = $counter + 1; ?>
0) echo ""; ?>
IP Address
Port size="5">
NOTE: Leave blank to use Frontend port selection.
Status
Cookie size="64">
This value will be checked in incoming requests, and the first operational server 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.
Weight size="64">
The default weight is 1, and the maximal value is 255.
NOTE: If this parameter is used to distribute the load according to server's capacity, it is recommended to start with values which can both grow and shrink, for instance between 10 and 100 to leave enough room above and below for later adjustments.
