Answer 1

Here's what i use (as of this monent in time):

using  System.IO.Compression;  public class CompressAttribute : ActionFilterAttribute {     public override void OnActionExecuting(ActionExecutingContext filterContext)     {          var encodingsAccepted = filterContext.HttpContext.Request.Headers["Accept-Encoding"];         if (string.IsNullOrEmpty(encodingsAccepted)) return;          encodingsAccepted = encodingsAccepted.ToLowerInvariant();         var response = filterContext.HttpContext.Response;          if (encodingsAccepted.Contains("deflate"))         {             response.AppendHeader("Content-encoding", "deflate");             response.Filter = new DeflateStream(response.Filter, CompressionMode.Compress);         }         else if (encodingsAccepted.Contains("gzip"))         {             response.AppendHeader("Content-encoding", "gzip");             response.Filter = new GZipStream(response.Filter, CompressionMode.Compress);         }     } } 

usage in controller:

[Compress] public class BookingController : BaseController {...} 

there are other varients, but this works quite well. (btw, i use the [Compress] attribute on my BaseController to save duplication across the project, whereas the above is doing it on a controller by controller basis.

[Edit] as mentioned in the para above. to simplify usage, you can also include [Compress] oneshot in the BaseController itself, thereby, every inherited child controller accesses the functionality by default:

[Compress] public class BaseController : Controller {...}
