copied!<p>What are the do's and don'ts about Cache VS Session VS Cookies?</p> <p>For example:<br> I'm using Session variables a lot and sometimes have problems in a booking-application when users start to order products and then go to lunch and come back some hours later and continue the booking. I store the booking in the session until the user confirms or aborts the booking so I don't need to talk to the database and handle halfway bookings in the database when users just click the X in the browser and never comes back.</p> <p>Should I instead use cache or cookies or some combination for this?</p> <p>(Also when there is some error in the app, the session-object resets itself and I get more problems because of that)</p> <p>I'm mostly doing desktop-programming and feel I lack lots of knowledge here so anyone who can expand on where to use Cache, Session, Cookies (or db) would be appreciated</p> <p><strong>Edit:</strong> From the answers it seems that a combination of DB and cookies is what I want. </p> <ol> <li>I have to store the booking in the database connected to a session-id </li> <li>Store the session-id in a cookie (encrypted). </li> <li>Every page load checking the cookie and fetch the booking from the database</li> <li>I have a clean-up procedure that runs once a week that clears unfinished bookings.</li> </ol> <p>I can't store the booking as a cookie because then the user can change prices and other sensitive data and I had to validate everything (can't trust the data).</p> <p>Have I got it right?</p> <p>And thanks for great explanations to all of you!</p>
