关于asp.net网站 gzip压缩 优化问题
本人对于优化就是菜鸟，以前从没接触过。求各位大哥帮忙啊， 我用asp.net做的网站 已经发布到ftp上。现在想对网站进行gzip压缩 ，提高浏览速度。由于条件限制不能用IIS进行GZIP压缩，只能写代码啦， 在网上也搜到了代码如下：
public sealed class CompressionModule : IHttpModule
{

    void IHttpModule.Dispose()
    {
        // Nothing to dispose; 
    }

    void IHttpModule.Init(HttpApplication context)
    {
        if (BlogSettings.Instance.EnableHttpCompression)
        {
            context.PreRequestHandlerExecute += 
                new EventHandler(context_PostReleaseRequestState);
        }
    }

    private const string GZIP = "gzip";
    private const string DEFLATE = "deflate";

    void context_PostReleaseRequestState(object sender, EventArgs e)
    {
        HttpApplication app = (HttpApplication)sender;
        if (app.Context.CurrentHandler is System.Web.UI.Page && 
            app.Request["HTTP_X_MICROSOFTAJAX"] == null)
        {
            if (IsEncodingAccepted(DEFLATE))
            {
                app.Response.Filter = 
                    new DeflateStream(app.Response.Filter,
                        CompressionMode.Compress);
                SetEncoding(DEFLATE);
            }
            else if (IsEncodingAccepted(GZIP))
            {
                app.Response.Filter = 
                    new GZipStream(app.Response.Filter,
                        CompressionMode.Compress);
                SetEncoding(GZIP);
            }
        }
        else if (app.Context.Request.Path.Contains("WebResource.axd"))
