AS3 file receive


We are in the process of developing a service for receiving files via AS3 protocol. When the customer posts a file to the /userFtpRoot//AS3/inbox and there should be a scheduler or polling port to fire the service as soon as the file comes.

My problem is, don’t want to create separate polling port or scheduler for each customer and most importantly, wanted to authenticate the customer via certificate only.

Is there any possibility of doing this via common method, like keeping one polling port or is there any other way to achieve the same.

Thanks & Regards,
