At left in the figure above are the expressions for the three match rules, shown in the order in
which they are configured in the cluster. At right, the decision tree describes how the match rules
are evaluated for every client request that comes into this cluster.
As described previously, the first match rule (
ma01
) is meant to match any request that does not
have a directory in it. Since this is our most common case, match rule evaluation will stop after
the first match rule is evaluated for the majority of incoming requests.
The second and third rules, ma02 and ma03 , match for specific directory names. We match for the
most common directory name first, then the less common directory name.
Finally, if all three of the match rule expressions for
ma01
,
ma02
, and
ma03
fail to match an
incoming request, then that request is load balanced across the server pool in the cluster using
the options set on the cluster (and mirrored in the Default match rule).
Match Rule Expressions and Bodies
Match functions and operators are used to construct the
expression
parameter found in a match
rule. The
expression
parameter selects the requests to be processed using the parameters
specified in the remainder of the match rule.
