Is there a web-based log-tailing application?

I have been using BareTail for low-footprint log reading, and it works wonderfully. In particular, I like that it can consume 开发者_如何学编程very large large files, detect changes to those files, all without consuming much memory at all.

I'd like to know if there are applications out there -- flash, java applet, etc -- that I could use in a web page to mimic this functionality in a program I'm writing

You can't do this client-side only, the tailing of the logfile has to be done on the server.

Here's an example in Python that's using AJAX.

This now possible thanks to ColdFusion 10 and Web sockets.
