I have been working on one project which lets users view online quotes of some stock prices. These get updated frequently and are reflected on the site in real time. Something like the TV Screens on the airport showing you airline information.

Ok, so basically, the client uploads (ftp's) an excel file every time they want to upload new quotes. This excel file is read by an ASP script which converts it into a text file which Flash can understand. Finally the webpage which is a flash page reads this text file and updates the quote prices.

My problem is running the ASP file everytime the excel file is uploaded. How can this be done automatically on the server side?
Any ideas? The flash file loops loops every 150 frames and reads the text file in the first frame.

Thanks in advance
