NetScaler http requests clone replication

When http requests to NetScaler, sometimes an external device is needed to analyze or record the request, so it is necessary to copy and clone the incoming http request. The original request goes to the selected server according to the judgment of NetScaler, while the copied HTTP request can be sent to any other server according to the demand.
