如何定义一个变量，每个页面都可以访问：（

[buyifly]

我想定义一个变量，siteName
变量值是从数据库中取得的网站名称
我想使每个页面的title是是<%=siteName%>
怎么定义才可以每个页面都使用呢？？

[MonkWang]

存储在Session里就可以啊

[buyifly]

不知道大伙做这类东东怎么搞的呢？？

不是很明白：（

[ice_frank]

用Session吧

[buyifly]

大伙都说用SESSOIN怎么做呢？：9
初学者， 不懂呀：（

[godwu]

Session.Item("xxx") = "aaaa"

用的时候取
例:dim strTemp as String = Session.Item("xxx")

而且SESSION可以存OBJECT类型

[buyifly]

谢谢！
你们的网站是这么做的吗？

[TScom]

比如记录登录用户的信息，就可以记在SESSION中。

[buyifly]

用户登陆信息我记在cookie中：（
可以吗？
