<a href="index_bblb_xx.aspx ? xx=aa " onclick="Session['aaa'] = 'aaa';">aaaaa</a>
在index_bblb_xx.aspx 获得页面参数 然后处理
这样应该灵活点

用个隐藏的input，设为服务器端运行， js可以访问它的值，后台代码C#也能访问

呵呵，楼主不会想像模拟登陆一样进入需要验证的网页吧？

呵呵，如果是这样恐怕难度有些大，呵呵。

JS里面好像不能用SESSION吧，学习一下

我的意思是
一个链接，点一下，生成一个session
但是因为这个连接又是动态生成的，所以不能用Attributes

不知道，你具体想做什么，照本人理解，是这样

些个隐藏域，把值付给隐藏域，然后在通过JS调用。
<input id="ok" type="hidden" runat="server">

.cs
if(Session['aaa']!=null)
{
ok.Value = Session['aaa'].ToString();
}
this.link1.Attributes.Add("onclick","javascript:check()");

.aspx
function check()
{
strValue = ok.value;
}

try
<a id="link1" href="index_bblb_xx.aspx" runat="server">aaaaa</a>

page_load
if(!Page.IsPostBack)
{
this.link1.Attributes.Add("onclick",Session['aaa'] = 'aaa');
}
