* Interceptor per la gestione degli "Aps Ajax Action Params",

* L'interceptor intercetta i parametri il cui nome รจ strutturato secondo la sintassi:<br />
* <ACTION_NAME>@<PARAM_NAME_1>=<PARAM_VALUE_1>;<PARAM_NAME_2>=<PARAM_VALUE_2>;....;<PARAM_NAME_N>=<PARAM_VALUE_N>
* <br />
* L'interceptor effettua il parsing della stringa inserendo i parametri estratti nella richiesta corrente
* in maniera tale che vengano intercettati dal successivo "Parameters Interceptor" di default del sistema.
