类名：WebCompressUtility.cs

代码如下：

/// <summary>
    /// Js、Css文件压缩辅助类
    /// Stone_W
    /// 2011.6.21
    /// </summary>
    public class WebCompressUtility
    {
        public WebCompressUtility() { }
    
        #region 判断浏览器是否支持指定压缩
        /// <summary>
        /// 判断浏览器是否支持指定压缩
        /// </summary>
        /// <param name="ctype">文件压缩类型</param>
        /// <param name="context">HttpContext对象</param>
        /// <returns>bool</returns>
        public static bool IsEncodingAccepted(CompressTypeEnum ctype, System.Web.HttpContext context)
        {
            if (null == context) return false;
            return null != context.Request.Headers["Accept-Encoding"] && context.Request.Headers["Accept-Encoding"].Contains(ctype.ToString());
        }
        #endregion
    
        #region 添加指定的压缩类型
        /// <summary>
        /// 添加指定的压缩类型
        /// </summary>
        /// <param name="ctype">文件压缩类型</param>
        /// <param name="context">HttpContext对象</param>
        public static void SetEncodingAccepted(CompressTypeEnum ctype, System.Web.HttpContext context)
        {
            if (null == context) return;
            context.Response.AddHeader("Content-encoding", ctype.ToString());
        }
        #endregion
    
    }
    
    /// <summary>
    /// 文件压缩类型
    /// </summary>
    /// example
    public enum CompressTypeEnum
    {
        gzip,
        deflate
    }

调用：

1.WebCompressUtility.IsEncodingAccepted(CompressTypeEnum.gzip, context);

2.WebCompressUtility.SetEncodingAccepted(CompressTypeEnum.gzip, context);

示例：

1
       
       
         
       
       
        if
       
       
         (WebCompressUtility.IsEncodingAccepted(CompressTypeEnum.gzip, context))
    
       
       
        2
       
       
         {
         
    
       
       
        3
       
       
             WebCompressUtility.SetEncodingAccepted(CompressTypeEnum.gzip, context);
    
       
       
        4
       
       
         }
