Solve the following python programming problem given the following code:
def logout(self, redirect_to = '/') : 
    '
        This property will return component which will handle logout requests.
        It only handles POST requests and do not display any rendered content.
        This handler deletes session id from `storage`. If there is no
        session id provided or id is incorrect handler silently redirects to
        login url and does not throw any exception.
        ' 
    def _logout(env, data) : 
        location = redirect_to 
        if ((location is None) and env.request.referer) : 
            location = env.request.referer 
else : 
            if (location is None) : 
                location = '/' 
response = HTTPSeeOther (location = str (location)) 
        self.logout_user (env.request, response) 
        return response 
return ((web.match ('/logout', 'logout') | web.method ('post')) | redirect_to) 

    
    

    Fix the buggy line: return ((web.match ('/logout', 'logout') | web.method ('post')) | redirect_to)
