title: What is the maximum file size I can transfer using HTTP? And using FTP?
body: <p><strong>Added</strong>: I am conducting a study for a new system we're going to develop in my work. It consists in authenticating users, displaying what files they want to download and downloading them. Also, if the files are not readily available, the user can't download them, but the server obtains a copy of the requested file and notifies the user by mail when he can get the file. We expect files to be tipically from 2 to 50 gigabytes in size, for now.</p>
  
  <p>I just want to check if it's possible to write a Web application to solve the problem or if we need to make a client-server solution.</p>
