The session.start() method returns a session object for the storage driver you chose. The session object can be treated like a dictionary to set and get variables. Any python object whcih can be pickled using the pickle module can be set in the session store.
Have a look at the example application below:
#!/usr/bin/env python # show python where the web modules are import sys sys.path.append('../') sys.path.append('../../../') import web, web.session, os session = web.session.start( storage='file', app='test', dir='../doc/src/lib/example-web-session', expire=10, ) print "Content-type: text/html\n\n" if session.created: print """<html> <h1>This is your first visit</h1> <p>Setting variable1 to 'Python Rules!'.</p> <p>Refresh this page...</p> </html>""" session['variable1'] = 'Python Rules!' else: if web.cgi.has_key('destroy'): session.destroy() print """<html><h1>Session Deleted</h1> <p><a href="%s">Start again</a>. </p></html>"""%(os.environ['SCRIPT_NAME']) else: print """<html><h1>Welcome back</h1><p>variable1: %s</p> <p><a href="%s?destroy=True">Destroy session</a>. </p></html>"""%(session['variable1'],os.environ['SCRIPT_NAME'])
You can test this example by running the webserver scripts/webserver.py and visiting http://localhost:8080/doc/src/lib/webserver-web-session-file.py
