title: What's a better solution for my shopping cart?
body: <p>I'm currently programming the shopping cart of my webshop and i was wondering what the best solution is to do this.</p>
  
  <p>I currently have 5 sessions that includes data of the items that have been added by the user to save sql stress. But i just read that using sessions isn't good for performance and that the server destroys sessions when the maximum has been reached (I've no idea what the maximum is and i don't expect that hundreds of users buy items at the same time, only a few). </p>
  
  <p>Conclusion, what's better to use 5 sessions to save data of the products or to use queries to get all the information of the products everytime the user visits the shopping cart?</p>
  
  <p>Any other suggestion is welcome as well!</p>
