I am trying to build a website in python webpy framework and I am having trouble in cache-control of web browser. When the user presses the back button of the browser it goes back to the userpage even though the user has logged out.

My code looks like this - it has errors but I am not sure how it is done 

class Logout:
    web.header("Cache-Control",
           "no-cache, max-age=0, must-revalidate, no-store")
    def GET(self):
        session.login=0
        session.kill()
        raise web.seeother('/')

Any help would be appreciated. I am actually looking for the python code because I have no idea where that "web.header" is to be placed.

You put your web.header directives inside the actual GET and SET methods on the classes.

So your case would be:

class Logout:

    def GET(self):
        web.header("Cache-Control", "no-cache, max-age=0, must-revalidate, no-store")
        session.login=0
        session.kill()
        raise web.seeother('/')
