Have been building a new site for a while and have several people doing testing. The site uses mini cart at the top of the page aswell as a main shopping cart page. If the user visits the shopping cart page they see the contents of their own cart in the main cart and the mini cart. If they then go to another page the mini cart occasionally populates with the contents of another users cart.
Any idea what might be causing this and how to fix it?
--- Edit
Further investigation has revealed that for some reason the session for one user is picking up the sessionKey for another user if they are both buying tickets at the same time.
Any thoughts?
