</HTML>在登陆后，访问其他页面时报500错误，好像是cookies没起作用，哪位高手指点一下，十分感谢

解决方案 »

  1.   

    如果cookies没起作用的话是否cookies被防火墙什么东西禁用了呢?不是很清楚..但是cookies这个东西不是很好用  有些客户的机器禁用了cookies那样比较麻烦
      

  2.   

    现在的问题是，模拟登陆后请求新的页面时，得到                                                     <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
