Adding Custom HTTP Headers to an ASP.NET MVC Response

Here's a little class I just put together to enable you to add HTTP Headers to a View in ASP.NET MVC 3.

It's pretty simple and I might quite easily have missed something very similar that is built in.

I do however like the idea of using an attribute for this rather than having a bunch of AppendHeader calls in the body of the Controller Action.

/// 
/// Represents an attribute that is used to add HTTP Headers to a Controller Action response.
/// 
public class HttpHeaderAttribute : ActionFilterAttribute
{
    /// 
    /// Gets or sets the name of the HTTP Header.
    /// 
    /// The name.
    public string Name { get; set; }

    /// 
    /// Gets or sets the value of the HTTP Header.
    /// 
    /// The value.
    public string Value { get; set; }

    /// 
    /// Initializes a new instance of the  class.
    /// 
    /// The name.
    /// The value.
    public HttpHeaderAttribute(string name, string value)
    {
        Name = name;
        Value = value;
    }

    public override void OnResultExecuted(ResultExecutedContext filterContext)
    {
        filterContext.HttpContext.Response.AppendHeader(Name, Value);
        base.OnResultExecuted(filterContext);
    }
}

You then use it like this:

[HttpHeader("X-Robots-Tag", "noindex")]
public ActionResult Edit(int id)
{
    // ...
}
