Simple way to compress Web API Response

There are many ways to do Web API Response compression. I particularly like Radenko Zec's solution mostly because it's simple and efficient.

A few steps I did in my project:

•  Pick your favorite compression tool. I used DotNetZip as Radenko recommended. It gives me close to 85% compression rate for JSON. A CompressionHelper is used as well so that I can easily change to a different compression tool if I want.
• Implement DeflateCompressionAttribute. Mostly Radenko's code:

    public class DeflateCompressionAttribute : ActionFilterAttribute

    {

        public override void OnActionExecuted(HttpActionExecutedContext actContext)

        {

            var content = actContext.Response.Content;

            var bytes = content == null ? null : content.ReadAsByteArrayAsync().Result;

            var compressedContent = bytes == null ? new byte[0] : CompressionHelper.Compress(bytes);

            actContext.Response.Content = new ByteArrayContent(compressedContent);

            actContext.Response.Content.Headers.Remove("Content-Type");

            actContext.Response.Content.Headers.Add("Content-encoding", "deflate");

            actContext.Response.Content.Headers.Add("Content-Type", "application/json");

            base.OnActionExecuted(actContext);

        }

    }

• Add [DeflateCompression] attribute to any WebAPI method needs compression
• Decompress using standard HttpClientHandler. As our Web API client is expecting objects, we configure HttpClientHandler to decompress response:

            using (var client = new HttpClient(new HttpClientHandler(){AutomaticDecompression = DecompressionMethods.Deflate|DecompressionMethods.GZip}))

            {

                var para = new ServiceParams();

                client.BaseAddress = new Uri(_serviceUrl);

                client.DefaultRequestHeaders.AcceptEncoding.Add(new StringWithQualityHeaderValue("gzip"));

                client.DefaultRequestHeaders.AcceptEncoding.Add(new StringWithQualityHeaderValue("deflate"));

                HttpResponseMessage response =

                    client.PostAsync(_servicePath, para, new JsonMediaTypeFormatter()).Result;

                r = response.Content.ReadAsAsync<ServiceResponse>().Result;

            }
