I want to compress my web application with Gzip and I am using following class
compression filter
public class CompressFilter : ActionFilterAttribute
{
public override void OnActionExecuting(ActionExecutingContext filterContext)
{
HttpRequestBase request = filterContext.HttpContext.Request;
string acceptEncoding = request.Headers["Accept-Encoding"];
if (string.IsNullOrEmpty(acceptEncoding)) return;
acceptEncoding = acceptEncoding.ToUpperInvariant();
HttpResponseBase 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);
}
}
}
cache filter
public class CacheFilterAttribute : ActionFilterAttribute
{
public int Duration
{
get;
set;
}
public CacheFilterAttribute()
{
Duration = 1;
}
public override void OnActionExecuted(ActionExecutedContext filterContext)
{
if (Duration <= 0) return;
HttpCachePolicyBase cache = filterContext.HttpContext.Response.Cache;
TimeSpan cacheDuration = TimeSpan.FromMinutes(Duration);
cache.SetCacheability(HttpCacheability.Public);
cache.SetExpires(DateTime.Now.Add(cacheDuration));
cache.SetMaxAge(cacheDuration);
cache.AppendCacheExtension("must-revalidate, proxy-revalidate");
}
}
controller
[CompressFilter]
[CacheFilter(Duration = 60)]
public ActionResult Index()
{}
and applying this class to Action in Controller. But in firebug it's still showing "Transfer-Encoding: chunked" , but it should be "Transfer-Encoding: gzip".
I am testing it on localhost.
Please tell me what am I doing wrong? Thanks and Regards.
update cache filter is working fine, but still no gzip compression, below is response header in chrome.
Cache-Control:public, must-revalidate, proxy-revalidate, max-age=3600
Content-Type:text/html; charset=utf-8

Is there any way I can make this work, I really need help guys, Thanks
If you can't control IIS, just add this to your Global.ASCX. tested on Android, iPhone, and most PC browsers.
protected void Application_BeginRequest(object sender, EventArgs e)
{
// Implement HTTP compression
HttpApplication app = (HttpApplication)sender;
// Retrieve accepted encodings
string encodings = app.Request.Headers.Get("Accept-Encoding");
if (encodings != null)
{
// Check the browser accepts deflate or gzip (deflate takes preference)
encodings = encodings.ToLower();
if (encodings.Contains("deflate"))
{
app.Response.Filter = new DeflateStream(app.Response.Filter, CompressionMode.Compress);
app.Response.AppendHeader("Content-Encoding", "deflate");
}
else if (encodings.Contains("gzip"))
{
app.Response.Filter = new GZipStream(app.Response.Filter, CompressionMode.Compress);
app.Response.AppendHeader("Content-Encoding", "gzip");
}
}
}
