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
