OK, I'm familiar with scanners such as that - although not that
particular one.
And yes, you can use active sync to transfer the file. But you don't
have to, either. For instance, you can put a program on the PDA which
handles the input from the scanner (which is still probably via a serial
port) to get the data, and to automatically connect with another
application on the PC to update the information.
But there is no way the server can search for files on a client machine.
Such access would be a tremendous security exposure. If you want to
automate this, you're going to have to use some method other than a
browser and web server.
And BTW - there are some very nice RF scanners out there with decent
range nowadays. You don't need the PDA and Active Sync.
