When you say the result is sent to "internal server" are you referring to the Internal Server reporting option that is specified in the Quiz > Reporting screen in Captivate?
If so, then you need to be aware that trying to use the Aggregator will disable that functionality. The Aggregator takes only the SWFs from the modules it bundles together and then adds its own HTM and JS file. This effectively strips away components required for the Internal Server reporting mechanism.
