Razor MVC3 Keeping Global Variable Set on return to view

Question

I have a global string variable that I set after one action is made (submit button is pressed) and then I want to access that same string when I press another button, currently I am doing something like

GlobalVariable = "blah";
return View();

What is the best practice for accessing this again. I would like to point out it is the same page(index.cshtml)

Thanks!

If its a per user value, use this:

Session["MyKey"] = "MyValue"; // save the value
var myValue = (string) Session["MyKey"]; // retrieve the value

If its one value for all users use this:

Application["MyKey"] = "MyValue"; // save the value
var myValue = (string) Application["MyKey"]; // retrieve the value

Hope this helps.
