Code

public static HttpContext compressResponsed(HttpContext context)
{
    string acceptEncoding = context.Request.Headers["Accept-Encoding"].ToString().ToUpperInvariant();
    if (!String.IsNullOrEmpty(acceptEncoding))
    {
        if (acceptEncoding.Contains("GZIP"))
        {
            context.Response.AppendHeader("Content-encoding", "gzip");
            context.Response.Filter = new GZipStream(context.Response.Filter, CompressionMode.Compress);
        }
        else if (acceptEncoding.Contains("DEFLATE"))
        {
            context.Response.AppendHeader("Content-encoding", "deflate");
            context.Response.Filter = new DeflateStream(context.Response.Filter, CompressionMode.Compress);
        }
    }
    return context;
}

使用方式

public void ProcessRequest(HttpContext context)

{

 context = Utlity.compressResponsed(context);

 // context.Response.Write(xxx)

}
