how to lock an asp.net mvc action?

Question

I\'ve written a controller and action that I use as a service. This service runs quite a costly action. I\'d like to limit the access to this action if there is already a cu

Answer 1

The simplest way to do that would be save to the cache a Boolean value indicating the action is running the required BL already:

if (System.Web.HttpContext.Current.Cache["IsProcessRunning"])
{
    System.Web.HttpContext.Current.Cache["IsProcessRunning"] = true;
    // run your logic here
    System.Web.HttpContext.Current.Cache["IsProcessRunning"] = false
}

Of course you can do this, or something similar, as an attribute as well.
