I'm not clear how this would work. If the servlet isn't threadsafe, how can the application be threaded? Are you proposing a model more like HTTPServlet, less like Page? Thread safety just seems like a burden to me -- if you want to share resources module globals or class variables are just as easy, and since it's not threadsafe you can also use instance variables. > The other aspect I like about Twisted is the "dispatch" mechanism > it uses to find a servlet; it is not only simple but extremely > flexible.

Can you give a pointer to that?

Yes, I added support less than a year ago (a couple months ago I think). If you look at WebKit/HTTPServer.py, it implements one example. There still isn't real support for non-HTTP requests (though you can fudge and shove other requests into HTTPRequest). That's probably fairly easy to fix. There's also an underlying assumption that transactions are more-or-less stateless, like HTTP. FTP support, for example, would probably involve a thread that held onto the state (and the connection), and pushes out requests to the AppServer. So it might make sense to trim the AppServer down and move the servers out of it.
