Secure Logut Script

[anups]

Hi All,

I am using HTTP Session2 pear module in my project.

My logout code is

HTTP_Session2::set('user_id','');
HTTP_Session2::set('user_type','');
HTTP_Session2::regenerateId(true);
HTTP_Session2::destroy();
pageRedirect("index.php?q=registration/login");
exit;

 

My Check Login Script is

if(trim(HTTP_Session2::get('user_id'))=='' || trim(HTTP_Session2::get('user_type'))=='') {
        HTTP_Session2::set('user_id','');
HTTP_Session2::set('user_type','');
HTTP_Session2::regenerateId(true);
HTTP_Session2::destroy();
pageRedirect("index.php?q=registration/login");
        exit;
}

 

 

problem here is whenever I click on back button after logout then I can see the user homepage, on which I have written "Check Login Script ".

 

Is there a good solution available ?
