Buongiorno a tutti del Forum!
Ho deciso di chiedere il vostro aiuto dopo una mattinata di ricerche infruttuose riguardo il mio problema.
Praticamente per un sito al quale sto lavorando avrei bisogno di uno script che acceda alla rete IRC, si colleghi ad un server, si logghi in un canale e scarichi un pack da un bot utilizzando il comando XDCC.
Dopo un po' di ricerche ho trovato uno script (che si chiama XDCC Fetcher e viene rilasciato con licenza GNU) che sembra fare al caso mio.
Infatti fa esattamente quello che ho detto: dato il server, il bot e il numero di pack comincia lo scaricamento...il mio problema è che salva il file su una cartella del server.
Quindi vengo alla mia domanda: è possibile fare in modo che il file venga invece salvato sul pc del client, ovvero con la classica finestra di dialogo che chiede dove salvare il file e poi comincia lo scaricamento?

Grazie a tutti per la disponibilità!!!
Di seguito trovate il codice delle pagine principali, comunque lo script è scaricabile interamente da http://webscripts.softpedia.com/scri...er--36626.html
