Whenever I need to write a web-application I do use jython and write 
servlets. This combines the power of Servlet/JSP with the worlds best 
programming language.

a jython servlet would look like this:

from javax.servlet.http import HttpServlet

class MyServlet(HttpServlet) :

	def doGet(self, request, response) :

		session = request.getSession(1)
		lang = session.getAttribute('language')
		if not lang :
			# initialise the session (i.e. choose language)

		# produce output suitable to lang
		if lang == 'DE' :
			print >> res.writer, "Hallo Welt!"
		else :
			print >> res.writer, "Hello World!"

There are other solutions. I believe that Zope offers session-management 
too.
