关于WEB.CONFIG配置SESSIONSTATE的一个小疑点

关于WEB.CONFIG配置SESSIONSTATE的一个小问题
在web.config内配置了sessionstate后,导致验证码文件无法显示图片了
如何能使验证码文件ValidateNum.aspx不进行session的验证呢?

<sessionState mode="InProc" cookieless="false" timeout="60" />

[解决办法]
验证码的..SESSION 配置...单独写 ...

ValidateBase.cs

C# code

using System;using System.Data;using System.Configuration;using System.Web;using System.Web.Security;using System.Web.UI;using System.Web.UI.WebControls;using System.Web.UI.WebControls.WebParts;using System.Web.UI.HtmlControls;namespace Security{    //该源码下载自www.51aspx.com(５１ａｓｐｘ．ｃｏｍ)    /// <summary>    /// ValidateBase 底层页    /// </summary>    public class ValidateBase : System.Web.UI.Page    {        public ValidateBase()        {                   }        /// <summary>        /// 存放验证码值        /// </summary>        public string strValidate        {            get            {                if (Session["ValidateCode"] != null)                    return Session["ValidateCode"].ToString();                else                    return "";            }            set            {                Session["ValidateCode"] = value;            }        }         }}
