Hi,

I use rewrite because there is a directive RewriteMap. With this directive I
can use external program to classify requests.
Other thing, the external program receive load information (CPU, RAM, etc..)
about cluster.

For example,
     If CPU > 80% then
         I drop request;
     else
         I pass the request to cluster (According to the classification is
selected a cluster)
.
Undestand ???

Thank you
Ricardo
