The Occasional Occurence

The most basic case is very simple.

import time
import cherrypy

class WebSvc(object):
    @cherrypy.tools.caching(delay=300)
    @cherrypy.expose
    def quadruple(self, number):
        time.sleep(1) # make the real call somewhat costly
        return str(int(number) * 4)

cherrypy.quickstart(WebSvc())

That uses an in-memory cache and defaults to items expiring from the cache in 300 seconds (5 minutes). If you want to tweak that setting or others you can configure the caching tool to your liking.

This is in response to `a post that asks if setting up caching in other web frameworks is as easy as in <http://slightlynew.blogspot.com/2009/02/full-web-service-with-http-caching-in-7.html>`_Rails` Ruby with Sinatra <http://slightlynew.blogspot.com/2009/02/full-web-service-with-http-caching-in-7.html>`_.
