ASP.NET和会话 - 新的浏览器与新浏览器窗口 [英] ASP.NET and Sessions - New Browser Instance versus New Browser Window

问题描述

我希望有人能澄清这个问题对我来说，并解释ASP.NET是如何决定何时对待像一个新的会话。

I'm hoping someone can clarify this behavior for me, and explain how ASP.NET is deciding when to treat something like a new Session.

A）在Internet Explorer中我加载有问题的ASP.NET站点。它启动一个新的会话。

B）如果我去菜单文件 - 新窗口...它保持在同一会话中
。
C）如果我启动Internet Explorer的新实例，并加载相同的页面开始新的会话。

A) In Internet Explorer I load the ASP.NET site in question. It starts a new Session.
B) If I go to menu File - New Window... it stays within the same Session.
C) If I launch a new instance of Internet Explorer and load the same page it starts a new Session.

我很困惑一步C.我期待它基于我的远程IP是同一个会话。

什么是IIS / ASP.NET做决定，这是一个新的会话？
难道是看着我的远程端口，IE浏览器的新实例使用？当你踢了一个新的窗口文件 - 新建使用相同的远程端口父

I'm confused by step C. I'm expecting it to be the same session based on my remote IP.
What is IIS / ASP.NET doing to decide that this is a new session? Is it looking at my remote port that the new instance of IE is using? When you kick up a new window with File - New it uses the same remote port as the parent.

推荐答案

在IIS / ASP.NET会话是基于与会话范围饼干，这意味着当浏览器被关闭，他们被摧毁，显然他们不共享在Internet Explorer中的不同的进程。

Sessions in IIS/ASP.NET are based on cookies with a session scope, meaning that they get destroyed when the browser is closed, and apparently they are not shared within different processes of Internet Explorer.

当你打开一个新的浏览器窗口，文件>新建窗口的窗口将被作为第一个相同的方法（即同一IEXPLORER.EXE）处理。当您从开始菜单劳克IE你得到一个新的过程，你现在必须在任务管理器以下两个IEXPLORER.EXE。我认为，这只是IE 7将产卵多个进程。

When you open a new browser window with File > New Window the window will be handled by the same process as the first (i.e. the same iexplorer.exe). When you lauch IE from the start menu you get a new process, and you will now have two iexplorer.exe in the Task Manager. I think that it's only IE 7 that will spawn multiple processes.

作为一个方面说明，IE 8将有每个标签/窗口，一个单一的过程，像谷歌Chrome浏览器了。我不知道如果这些浏览器共享amongs过程会话cookie，但它肯定是使用这些浏览器中的一个测试时要记住。

As a side note, IE 8 will have have a single process per tab / window, like Google Chrome has. I don't know if these browsers share session cookies amongs the processes, but it's certainly something to keep in mind when testing using one of these browsers.
