How to enable Gzip compression

Hi ,

Maybe two ways you can try :

1. In your code

Here is a simple example

public class GZipOrDeflateAttribute:ActionFilterAttribute
{
public override void OnActionExecuting
(ActionExecutingContext filterContext)
{
string acceptencoding = filterContext.HttpContext.
equest.Headers["Accept-Encoding"];
if (!string.IsNullOrEmpty(acceptencoding))
{
acceptencoding = acceptencoding.ToLower();
var response = filterContext.HttpContext.Response;
if (acceptencoding.Contains("gzip"))
{
response.AppendHeader("Content-Encoding", "gzip");
response.Filter = new GZipStream(response.Filter,
CompressionMode.Compress);
}
else if (acceptencoding.Contains("deflate"))
{
response.AppendHeader("Content-Encoding", "deflate");
response.Filter = new DeflateStream(response.Filter,
CompressionMode.Compress);
}
}
}
}

And the usage :

[GZipOrDeflate]
public ActionResult Index()
{
using (NorthwindEntities db = new NorthwindEntities())
{
return View(db.Customers.ToList());
}
}

2. Enable Compression in IIS

In Features View, double-click Compression. Then you will enter the

Compression page

In Compression page , you can enable the compression.
