Working with Clusters and Match Rules
Match bodies specify the actions to take if the match expression selects the request. This is
specified in the form of statements that provide values to variables used by the load balancer to
process the request. The most common (and most useful) match body selects the set of servers
(server pool) over which to apply the load balancing.
The
servers
assignment statement takes a comma-separated list of server names, which specifies
the set of servers to be used for load balancing all requests that match the expression in the
match rule. The reserved server names
all
and
none
specify respectively the set of all servers in
the virtual cluster and none of the servers in the virtual cluster. If you do not assign servers, none
will be available for load balancing; as a result, the connection to the client will be dropped.
In general, you can override most cluster-specific variables in a match body. One useful example
of overriding variables is as follows:
flags =!once_only;
which would load-balance across the specified server pool (which first must be defined in the
virtual cluster) and also turn off the
once_only
flag for the duration of processing of that
connection.
