Система GZip.сеть.пакеты оптимизации

С последним классом ASP.NET Optimization (v1.1.2) класс GZipTransform работает не очень хорошо.

Я нашел новый способ с пользовательским классом Bundle, который всегда будет сжимать содержимое пакета (которое было преобразовано и кэшировано) перед ответом:

public class GZipBundle : Bundle
{
    public GZipBundle(string virtualPath, params IBundleTransform[] transforms)
        : base(virtualPath, null, transforms) { }

    public override BundleResponse CacheLookup(BundleContext context)
    {
        if (null != context) GZipEncodePage(context.HttpContext);
        return base.CacheLookup(context);
    }

    // Sets up the current page or handler to use GZip through a Response.Filter.
    public static void GZipEncodePage(HttpContextBase httpContext)
    {
        if (null != httpContext && null != httpContext.Request && null != httpContext.Response
            && (null == httpContext.Response.Filter
            || !(httpContext.Response.Filter is GZipStream || httpContext.Response.Filter is DeflateStream)))
        {
            // Is GZip supported?
            string acceptEncoding = httpContext.Request.Headers["Accept-Encoding"];
            if (null != acceptEncoding
                && acceptEncoding.IndexOf(DecompressionMethods.GZip.ToString(), StringComparison.OrdinalIgnoreCase) >= 0)
            {
                httpContext.Response.Filter = new GZipStream(httpContext.Response.Filter, CompressionMode.Compress);
                httpContext.Response.AddHeader("Content-Encoding", DecompressionMethods.GZip.ToString().ToLowerInvariant());
            }
            else if (null != acceptEncoding
                && acceptEncoding.IndexOf(DecompressionMethods.Deflate.ToString(), StringComparison.OrdinalIgnoreCase) >= 0)
            {
                httpContext.Response.Filter = new DeflateStream(httpContext.Response.Filter, CompressionMode.Compress);
                httpContext.Response.AddHeader("Content-Encoding", DecompressionMethods.Deflate.ToString().ToLowerInvariant());
            }

            // Allow proxy servers to cache encoded and unencoded versions separately
            httpContext.Response.AppendHeader("Vary", "Content-Encoding");
        }
    }
}

// Represents a bundle that does CSS minification and GZip compression.
public sealed class GZipStyleBundle : GZipBundle
{
    public GZipStyleBundle(string virtualPath, params IBundleTransform[] transforms) : base(virtualPath, transforms) { }
}

// Represents a bundle that does JS minification and GZip compression.
public sealed class GZipScriptBundle : GZipBundle
{
    public GZipScriptBundle(string virtualPath, params IBundleTransform[] transforms)
        : base(virtualPath, transforms)
    {
        base.ConcatenationToken = ";" + Environment.NewLine;
    }
}

Затем вы можете использовать GZipStyleBundle и GZipScriptBundle для замены исходных классов Bundle.: StyleBundle, ScriptBundle. Пример:

public static class BundleConfig
{
    // For more information on Bundling, visit http://go.microsoft.com/fwlink/?LinkId=254725
    public static void RegisterBundles(BundleCollection bundles)
    {
        bundles.Add(new GZipScriptBundle("~/bundles/jquery.js").Include(...));
        bundles.Add(new GZipScriptBundle("~/bundles/jquery-ui.js", new JsMinify()).Include(...));

        bundles.Add(new GZipStyleBundle("~/bundles/all.css", new CssMinify()).Include(...));
    }
}

Это может быть достигнуто с помощью HttpModule

public class GzipModule : IHttpModule
{
    #region IHttpModule Members

    public void Init(HttpApplication application)
    {
        application.BeginRequest += Application_BeginRequest;
    }

    public void Dispose()
    {
    }

    #endregion

    private void Application_BeginRequest(Object source, EventArgs e)
    {
        HttpContext context = HttpContext.Current;
        HttpRequest request = context.Request;
        HttpResponse response = context.Response;
        string acceptEncoding = request.Headers["Accept-Encoding"];

        if (String.IsNullOrEmpty(acceptEncoding))
            return;

        acceptEncoding = acceptEncoding.ToUpperInvariant();

        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);
        }
    }
}

И зарегистрировать его в config

  <system.webServer>
    <modules>
        <add name="Gzip" type="Gecko.Web.GzipModule" />
    </modules>
