http://tus.io/ tus is a new open protocol for resumable uploads built on HTTP. It offers simple, cheap and reusable stacks for clients and servers to solve the problem of unreliable file uploads once and for all.
Currently, there are only two implementations of server side --- Go and Node.js. I wish the popular server --- Tomcat which is also my favorite can also implement this new file transfer protocol, too. -- Sincerely yours, Anita
