Is there some way to implement tail -f in JS?

I am loading log data over ajax, but it always flashes away then, so i need to find out what content was already there and append only the new content. Is there a framework for this?

You can obtain length of the file with HEAD and a part of it with range request

ajax = request-response. What you want is server push - e.g. via WebSockets
