title: SFTP server pushing data to http backend
body: <p>This is a bit of a strange requirement.
  I need an SFTP server, which uses http endpoint as a back-end instead of file system.</p>
  <p><a href="https://github.com/apache/mina-sshd/blob/master/docs/sftp.md" rel="nofollow noreferrer">Apache mina</a> is one possible candidate, sine it provides <code>SftpEventListener</code> with handler which has access to payload being transferred.</p>
  <p>There are few other solutions, which has different storage backends. Http support is not out of the box for those.</p>
  <p>proftpd and sftpplus also has hooks, which could be used to communicate with http endpoint, but still primary storage is a disk. Hopefully I'm looking for complete switch of the back-ends from disk-&gt;http.</p>
  <p>Can you point me if such solutions exists, or a solution which can be customized.</p>
  <p>Thanks</p>
