POST file - not from client machine, from web/ftp server

Question

I'm using .Net.

Is it possible for a web form to upload an image from a web or FTP server? The files I need to submit are on the web. If this is possible, code snippet is appreciated.

Answer 1

Yes, it is possible.

You can use the WebClient class to interact with other web servers in .Net server-side code.

For example:

using(var client = new WebClient())
    client.UploadFile("ftp://server/path", @"C:\path\to\file");

If the file is on a different website, you can write the following:

using(var client = new WebClient())
     client.UploadData("ftp://server/path", client.DownloadData("http://server/path"));

You can read and write FTP, HTTP, and HTTPS urls interchangeably.
