is it possible to upload a file to server2 using server1?
the visitor go to: mywebsite.com (server1)
then he upload a file to server1 and the server1 automatically upload that file to server2 ??
or simply is it possible to the user to upload a file to server2 using server1 as a proxy, because server2 is only accessable from server1
would ftp
be helpful or is there another better solution?
