Ok, I am trying to implement something like this, if anyone can give any idea.

So, we all know that using input type "file" we can upload file to server. What I want is a reverse.

So, I open the web-page and it will ask me for location of file or folder( on client machine) .Once I hit submit, server will start reading that folder and copy file from client. I guess this could give me ability to pause upload . 

This is my idea: On successful login I can connect to client via SCP and on success I will run copy command.

Is I am thinking in right direction, and/or if someone give me me little idea

Thanks
