Has anyone been able to force download a PDF for example and how is it best to get the full file path?

    var link = Model.Value<Link>("pathToPDFFile");
//var filePath = @link.Url;
var filePath = Request.PhysicalApplicationPath + @link.Url;

Response.AddHeader("Content-Type", "application/pdf");

// Set the filename and attachment disposition
Response.AddHeader("content-disposition", "attachment;filename=" + (filePath));
Response.Write(filePath);

// End the response
Response.End();
