ASP的SESSION问题

[alphahong]

页面里面调用的代码（另一个文件）里面包含了生成SESSION（a)，结果打印出来的SESSION却是上一个SESSION（a)的值。怎么解决，大家

[blacksun2000]

先把session(a)赋值为空，然后再把你想要赋的值给他看看。

[arrowy]

你的页面里Session是当前页生成的还是前面就有的?

[mymyal123]

先清空

session(a)=""
session(a)=xxx

[alphahong]

当前页面的没有任何SESSION生成的，调用的页面才生成SESSION，所以第一次访问的时候的答应不出SESSION的，要第二次刷新才能打印出来，然后显示的都是上一次的SESSION.

[possible_Y]

被include的文件和主文件的变量是共用的

并且对于同一客户端Session本来就是共用的

[jarraytan]

对啊,session对象同用户端共用,application对象整个服务器用户共用!

[alphahong]

是啊，所以我才想不懂。程序如下：

1.asp
-----------------
<b><font color=#ff0000 style="font-size:16px "><img src="xbm.asp">
<%response.Write""&Session("validateCode")
%>
</font></b>

Session("validateCode")
只发现了一个Session("validateCode")啊，你哪有重新赋值啊？没有重新赋值，当然显示的还是Session("validateCode") = num 啦！

[alphahong]

是啊，你运行试试就知道了，会发现打印出来的SESSION("VALIDATECODE")是刷新前的值

[scoutlin]

这个验证码程序我一直在用，没发现有楼主的问题

[cq_tan]

这是什么的验证程序?

[alphahong]

我的确是出现这样的问题，要不大家试试。有人知道为什么吗？
