logout session revisiting pages codeigniter

Question

The problem is after i logout, then press back button or go to user_control/login, then refresh, i wasn't redirected to the log in page but rather at the home page.

I unset and destroyed the session already.

One solution i found from the web is no cache. It works but it prompts for the resubmission of form and when i refresh i wasn't redirected to the login page but rather at the home page.

> controller: user_control 
> function: login 
> algorithm:
>      1. form validation set rules
>      2. get posts of username and password
>      3. check if the username is in the database and entered password is equal to the password in the database, if true go to 4. else go to signin page.
    >  4. set session
    >  5. load view home.php

I suspect, everytime i press the back button, the post request is still there, and when i refresh, it calls the user_control/login with the posts credentials of the form.

You need to restrict your home page or any other pages to only logged in users. Redirect others to the login page. Have a look at Ion Auth documents for an example of how this can be done.
