ruby web servers, threads and sessions

Is there a pure ruby web server that can start a thread that performs
some task and store it in a session allowing the user to control the
task from the browser? Similar to a what I can do with a java web
server?

Your question isn't crystal clear, but look at webrick, see if it's what you
have in mind. Webrick is included in a standard Ruby installation.

WEBrick + your custom code.

Ah, looks pretty straight forward, thanks.

Ok, so is it realistic to start up a Drb server and store it in a
session? Really what I am looking to do is to be able to control ruby
applications on various hosts from a web client using the web server as
the central hub.

The basic idea is a distributed log scanner app where the user can
control (add files, remove files, change search string) "scanning
agents" that are running on different hosts.

Yes, you can do this, but if the purpose is to govern the behavior of remote
machines, and if there are any security issues, I personally would do it
using SSH instead.

You could set things up to tunnel the webrick content through an SSH
connection. That is a way to balance ease of use with good security.

I am not perfectly clear about what you are trying to accomplish, but if
your description is a suitable guide, then maybe a text-based SSH remote
execution approach might be better than one based on a a Web server.

Thanks for the responses. It's all over the LAN, so security isn't a
concern at this point. I'll guess I'll go ahead with my initial idea.
I really haven't done much web/web based programming (or distributed
programming, really, apart from basic sockets), so any other
suggestions are welcome.
