    <p>Im trying to change all my ASP MVC HTTP response headers to have another value by default for implementing Pingback auto-discovery in my blog application.</p> <p>The default header (on Cassini) is :</p> <pre><code>Cache-Control private Connection Close Content-Length 20901 Content-Type text/html; charset=utf-8 Date Fri, 20 Apr 2012 22:46:11 GMT Server ASP.NET Development Server/10.0.0.0 X-AspNet-Version 4.0.30319 X-AspNetMvc-Version 3.0 </code></pre> <p>and i want an extra value added : </p> <pre><code>X-Pingback: http://localhost:4912/pingback/xmlrpcserver </code></pre> <p>I have googled a bit and found a neet solution : -- to derive from <strong>ActionFilterAttribute</strong> and override the <strong>OnResultExecuted</strong> method:</p> <pre><code>public class HttpHeaderAttribute : ActionFilterAttribute { public string Name { get; set; } public string Value { get; set; } public HttpHeaderAttribute(string name, string value) { Name = name; Value = value; } public override void OnResultExecuted(ResultExecutedContext filterContext) { filterContext.HttpContext.Request.Headers.Add(Name, Value); base.OnResultExecuted(filterContext); } } </code></pre> <p>And then simply i put the attribute on my Controllers methods:</p> <pre><code>[HttpHeader("X-Pingback","http://localhost:4912/pingback/xmlrpcserver")] public ActionResult Index() { var allArticles = _repository.GetPublishedArticles(SortOrder.desc); return View(allArticles); } </code></pre> <p>When i runt the app i get the following error : <img src="https://i.stack.imgur.com/mhIor.jpg" alt="enter image description here"></p> <p>Any ideas?</p>

Guidance
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).
