How do I store data between requests in ASP.NET MVC?

My application reads barcodes from a USB scanner. I treat them as tokens and then build commands from those tokens. There may be a situation that I need 2 or more reads before I can create a command. I need to store previous reads in some way. How can I keep some data between request? I do not to use that tokens in my view.

Only results of commands may be displayed in the view.

The TempData dictionary is ideal for storing data between controller actions. It's most commonly used in the Post/Redirect/Get pattern but could apply here.

This is a good article to read about it: http://www.devcurry.com/2012/05/what-is-aspnet-mvc-tempdata.html

Here are a couple of possibilities that come to mind:

On the client:

  • Cookie
  • Hidden fields

On the server:

  • Cache (make sure to use user specific key to avoid collisions)
  • Some backend storage (such as a database)
  • ASP.NET Session
