    <p>It seems that what you are trying to accomplish is already built into ASP.NET MVC.</p> <p>I would use the [Authorize] attribute (<a href="http://msdn.microsoft.com/en-us/library/system.web.mvc.authorizeattribute(v=vs.108).aspx" rel="nofollow noreferrer">http://msdn.microsoft.com/en-us/library/system.web.mvc.authorizeattribute(v=vs.108).aspx</a>) where you want to check if the user has a cookie. </p> <p>If you want to redirect the user to a specific controller/action when the user is not authorized, you can use the following attribute instead:</p> <pre><code>public class AuthorizeUserAttribute : AuthorizeAttribute { protected override void HandleUnauthorizedRequest(AuthorizationContext filterContext) { filterContext.Result = new RedirectToRouteResult( new RouteValueDictionary( new { controller = "Error", action = "Unauthorized" }) ); } } </code></pre> <p>See <a href="https://stackoverflow.com/questions/13264496/asp-net-mvc-4-custom-authorize-attribute-with-permission-codes-without-roles">ASP.NET MVC 4 Custom Authorize Attribute with Permission Codes (without roles)</a></p> <p>Then you would use it by using:</p> <pre><code>[HttpPost] [AuthorizeUser] public ActionResult Save(Person oPerson) { return View(); } </code></pre> <p>Or if you want exactly what you asked for you can do it this way:</p> <pre><code>public class CheckCookieAttribute : ActionFilterAttribute, IActionFilter { public override void OnActionExecuting(ActionExecutingContext filterContext) { if (filterContext.HttpContext.Request.Cookies["YourCookie"] == null) { filterContext.Result = new RedirectToRouteResult(new RouteValueDictionary { {"controller", "MyController"}, {"action", "MyAction"}}); } else { base.OnActionExecuting(filterContext); } } public void OnActionExecuted(ActionExecutedContext filterContext) { //The action filter logic - after } } </code></pre>

    2. COBasically that's what [AuthorizeUser] does (and validates the cookie and so on), but if you want to check for a specific cookie set on the client, you can use the last code snippet in the answer.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
