I am trying to run Wroxshop shopping cart application from chapter 13 of Beginning with ASP.NET 2.0 C#. When I execute and open the URL in two different browser instances than both of them shows item in view shopping cart and addition or deletion of items in one browser instance gets reflected in another instance too. How can i change it so that if i add an item in one browser instance it should not get added in the shopping cart of another browser instance.

Please suggest some idea.

Thanks.

Hi there,

If I am not mistaken, the Shopping Cart is based on the Profile feature of ASP.NET 2.0. Profile by default relies on cookies. Cookies are shared between browser windows you open with Ctrl+N or Ctrl+T (in IE at least, that is).

So, you're looking at a lot of default behavior here. Without some extensive rewriting of the application, you won't be able to do this.

Hello Imar,
         Thanks for your reply. Do you mean to say that this is not possible with Profile and i have to use something like CookieCollection or session. Can you please suggest me the best way of how to implement that without changing a lot in the code. Can i change some settings in web.config or global.asax to achieve that behaviour of temporary shopping cart.

Thanks,
Nilesh

Correct. By default, Profile relies on cookies, and so cookies itself, and session state as well. Moving away from Profile to cookies or session state gives you the same problems.
