Need help with GZIP Compression

    Hi,
    I came across an article which said that one should compress one's files when fetched from server because that really speeds up the site loading time.
    SEMrush
    Currently, in my Global.asax file , I am using the following code :

     void Application_PreRequestHandlerExecute(object sender, EventArgs e)
        {
    
            HttpApplication app = sender as HttpApplication;
            string acceptEncoding = app.Request.Headers["Accept-Encoding"];
            Stream prevUncompressedStream = app.Response.Filter;
    
            if (!(app.Context.CurrentHandler is Page ||
                app.Context.CurrentHandler.GetType().Name == "SyncSessionlessHandler") ||
                app.Request["HTTP_X_MICROSOFTAJAX"] != null)
                return;
    
            if (acceptEncoding == null || acceptEncoding.Length == 0)
                return;
    
            acceptEncoding = acceptEncoding.ToLower();
    
            if (acceptEncoding.Contains("deflate") || acceptEncoding == "*")
            {
                // defalte
                app.Response.Filter = new DeflateStream(prevUncompressedStream,
                    CompressionMode.Compress);
                app.Response.AppendHeader("Content-Encoding", "deflate");
            }
            else if (acceptEncoding.Contains("gzip"))
            {
                // gzip
                app.Response.Filter = new GZipStream(prevUncompressedStream,
                    CompressionMode.Compress);
                app.Response.AppendHeader("Content-Encoding", "gzip");
            }
    
    
        } 
    Code (markup):
    The following code compresses the html and aspx files but doesnt compress with JS and CSS..
    So kindly you could provide me with some snippet or point me in the correct direstion.

    Thanks

    add this code to your web.config
    <system.webServer>
    <httpCompression directory="%SystemDrive%\inetpub\temp\IIS Temporary Compressed Files">
    <scheme name="gzip" dll="%Windir%\system32\inetsrv\gzip.dll"/>
    <dynamicTypes>
    <add mimeType="text/*" enabled="true"/>
    <add mimeType="message/*" enabled="true"/>
    <add mimeType="application/javascript" enabled="true"/>
    <add mimeType="*/*" enabled="false"/>
    dynamicTypes>
    <staticTypes>
    <add mimeType="text/*" enabled="true"/>
    <add mimeType="message/*" enabled="true"/>
    <add mimeType="application/javascript" enabled="true"/>
    <add mimeType="*/*" enabled="false"/>
