Uploading and Downloading files

[Nitin Dubey]

Hi,
In a three tier architecture my client is sitting anywhere on the net. In one of his page he can upload a local file to his folder on the server. My middleware has to download the file from the client and upload to his folder on the server.
I can get the physical path of the local file in a text box from the client's page. Now how do I download the file from the client's machine and upload It to his folder on another server.
Your Suggesstions are welcome
