类名：WebCompressUtility.cs

代码如下：

/// <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 }
