Uploading files to a remote web server.

Hi guys, I hope you can help me with this problem. Any of you can tell me How can I do for uploading files of a client machine to my remote web server??. I've been trying to use the FileUpload control and its method "SaveAs()", but it doesn't work. How can I refer to the remote direction of my web server into the parameter of "FileUpload.SaveAs()" method??? I mean, there's a mthod for acquiring the IP server Addres or server name in order to establish the path for saving the file. In general terms, How can I upload a file to a remote server?? Thanks in advance.
