传统的ASP：多个ASPSESSIONID在饼干 [英] Classic ASP: Multiple ASPSESSIONID in cookies

问题描述

我有一个传统的ASP页面的一个问题，我只是解决不了它，因为3天。

I have a problem with a classic asp page and I just cannot solve it since 3 days.

该页面正在与会话 - 有时它发生的ASPSESSIONID饼干在Request.ServerVariables设置两次（HTTP_COOKIE）。这将导致ASP页到两次会议之间跳转的页面被刷新时。

The page is working with Sessions - sometimes it happens that the ASPSESSIONID cookie is set twice in the Request.ServerVariables("HTTP_COOKIE"). This causes the ASP-Page to jump between the two Sessions when the page is refreshed.

我已经写它输出当前的SessionID，服务器软件和HTTP_COOKIE值的测试页。

I have written an Test page which outputs the current SessionId, the Server Software and the HTTP_COOKIE value.

示例输出：

会话ID：308542840

Session ID: 308542840

会话超时：20分

服务器软件：Microsoft-IIS / 6.0

Server Software: Microsoft-IIS/6.0

HTTP_COOKIE：ASPSESSIONIDQCBATRAD = MBHHDGCBGGBJBMAEGLDAJLGF; ASPSESSIONIDQCCDTTCB = PGHPDGCBPLKALGGKIPOFIGDM

HTTP_COOKIE: ASPSESSIONIDQCBATRAD=MBHHDGCBGGBJBMAEGLDAJLGF; ASPSESSIONIDQCCDTTCB=PGHPDGCBPLKALGGKIPOFIGDM

为什么有两个ASPSESSIONIDs？
当我刷新页面，然后它随机输出两个Session ID之一。

Why are there two ASPSESSIONIDs? When I refresh the page then it randomly outputs one of the two Session IDs.

下面是一个截屏，显示在IE9的问题：

Here is a screencast which shows the problem in IE9: http://prinz-alexander.at/asp_test.avi

这个错误通常发生在IE8和IE9。

This error often occurs in ie8 and ie9.

只要做到以下重现问题：

Just do the following to recreate the Problem:

1. 完全关闭IE8或IE9


2. 启动IE8或IE9和开放 http://www.pfiffikus.at/pfiffikus/tests/


3. 后立刻加载页面刷新页面多发时间

如果您重复此步骤，然后随机（不总是）在HTTP_COOKIE填充了两种不同的ASPSESSIONIDs。

If you repeat this steps then randomly (not always) the HTTP_COOKIE is populated with two different ASPSESSIONIDs.

在ASP测试文件只在允许输出值mentiod，没有别的发生在源$ C ​​$ C。

The asp test file is only outputing the mentiod values, nothing else is happening in the source code.

这是asp的测试文件的code：

This is the code of the asp test file:

<% If trim(Session("test_val")) = "" Then
     Dim my_num
     Randomize
     number = Int((rnd*1000))+1
     Session("test_val") = number
   End If
%>

<b>Session ID:</b>
<% response.write(Session.SessionId) %><br /><br />

<b>Session("test_val"):</b>
<% response.write(Session("test_val")) %><br /><br />

<b>Session Timeout:</b>
<% response.write(Session.Timeout) %> minutes<br /><br />

<b>Server Software:</b>
<% response.write(Request.ServerVariables("SERVER_SOFTWARE")) %><br /> <br />

<b>HTTP_COOKIE:</b> <% response.write(Request.ServerVariables("HTTP_COOKIE")) %>

我怎样才能避免多重ASPSESSIONIds在饼干？

How can i avoid multiple ASPSESSIONIds in cookies?

感谢您的帮助！

推荐答案

我能够删除这些cookie使用Javascript。

I was able to remove those cookies with Javascript.

只是下一个脚本添加到登录页面的末尾。
这将删除所有的ASPSESSIONIDXXXXXXX饼干之前用户登录网站：

Just add next script to the end of login page. This will remove all "ASPSESSIONIDXXXXXXX" cookies before user will login to website:

<script type="text/javascript">
    //Clear any session cookies
    (function(){
        var i;
        var cookiesArr;
        var cItem;

        cookiesArr = document.cookie.split("; ");
        for (i = 0; i < cookiesArr.length; i++) {
            cItem = cookiesArr[i].split("=");
            if (cItem.length > 0 && cItem[0].indexOf("ASPSESSIONID") == 0) {
                deleteCookie(cItem[0]);
            }
        }

        function deleteCookie(name) {
            var expDate = new Date();
            expDate.setTime(expDate.getTime() - 86400000); //-1 day
            var value = "; expires=" + expDate.toGMTString() + ";path=/";
            document.cookie = name + "=" + value;
        }
    })();
</script>
