You can create Controller for Media

Hi Dileep, 

Using the below code you can redirect to a visitor on the 404 pages when it will click on the pdf link on page.

    [ContentType(DisplayName = "PdfFile", GUID = "21ffdb5d-a602-4d33-9da6-a2a0888b1937", Description = "Upload media file")]
    [MediaDescriptor(ExtensionString = "pdf")]
    public class PdfFile : MediaData
    {
      
    }

if you want custom processing before sending the media to the visitor, the example below shows how you can implement your own HTTP handler for PDF type media.

    public class CustomFileHandler : IHttpHandler, IRenderTemplate<PdfFile>
    {
        private readonly IContentRouteHelper _contentRouteHelper;
        private readonly IAccessDeniedHandler _accessDeniedHandler;

        // we need to provide a parameterless constructor
        public CustomFileHandler(IContentRouteHelper contentRouteHelper, IAccessDeniedHandler accessDeniedHandler)
        {
            _contentRouteHelper = contentRouteHelper;
            _accessDeniedHandler = accessDeniedHandler;
        }

        public CustomFileHandler() : this(ServiceLocator.Current.GetInstance<IContentRouteHelper>(), ServiceLocator.Current.GetInstance<IAccessDeniedHandler>())
        {
        }

        public bool IsReusable => false;

        public void ProcessRequest(HttpContext context)
        {
            //Get file content
            var content = _contentRouteHelper.Content;
            var mediaContent = content as MediaData;
            if (mediaContent == null || mediaContent.MimeType.Contains("application/pdf"))
            {
                throw new HttpException(404, "Not Found.");
            }

            //Check access
            if (!content.QueryDistinctAccess(AccessLevel.Read))
            {
                _accessDeniedHandler.AccessDenied(new HttpContextWrapper(context));
                return;
            }

            //Cast to custom file
            var customFile = content as PdfFile;
            if (customFile?.BinaryData == null)
            {
                throw new HttpException(404, "Not Found.");
            }

            //Set caching policy
            context.Response.Cache.SetCacheability(HttpCacheability.Private);
            context.Response.Cache.SetMaxAge(TimeSpan.FromDays(1));

            //Do custom processing
            //TransmitProcessedFile(customFile.BinaryData)
        }
    }

Thanks,

Hi Sanjay,
Thanks for the information. I started on similar route and tried to route the user to my custom access denied page instead of _accessdeniedhanler.AccessDenied method and it supposedly worked fine. But in the events of where user had access to file, the file was rendered as blank. Not sure if I have to add something in TransmitProcessedFile or if there is an implementation of it to just render the file as usual

Hi Dileep and Sanjay,

Did you ever figure out how to default to the custom episerver file rendering if the custom authorization passes? I do not need to do any custom processing and would like to render it as it would normally.
