I'm wondering what you guys think about this idea and if it will be secure.

Once the user logs in, assign the user a random number that will go in the URL with the GET method. Create a small temp file that contains the username, random number, and user IP. When someone loads a page, check for user IP and random number, and compare with the file information. Overwrite the temp file with a new random number (and maybe new IP) every time the user logs in. (You could add a sign-out function that will delete the temp file.)

How secure will that method be?
