ASP.NET环境中的共享变量 [英] Shared variables in ASP.NET environment
问题描述
IIS上的ASP.NET体系结构的结果刚刚回归到了家里，并且带来了很大的价值。它与共享变量有关。考虑这样一个模块：
公共模块函数
Public GlobalName As String''这对全局无效
应用程序对象
结束模块
由于所有用户共享一个aspnet_wp.exe进程，所有用户都会
访问相同的GlobalName变量。因此，如果用户A运行应用程序并且
将其设置为Fred。并且用户B将其设置为Bert，然后用户A看到新的
值？
这是正确的吗？
干杯，Rob。
A consequence of the ASP.NET architecture on IIS has just hit home with a
big thud. It''s to do with shared variables. Consider a module like this:
Public Module Functions
Public GlobalName As String '' this is ineffect a global
application object
End Module
As there is one aspnet_wp.exe process shared by all users, would all users
access the same GlobalName variable. So if user A runs the application and
sets it to "Fred" and user B sets it to "Bert", then User A sees the new
value?
This this right?
Cheers, Rob.

回答我自己的问题，但是，这就是发生的事情。所有用户访问
相同的共享变量......
干杯，Rob。
Answering my own question but yes, this is what happens. All users access
the same shared variables...

您好，
将它存储在会话状态。
会话（" GlobalName"）=" Rob Nicholson"

Hi,
Store it in session state.
Session("GlobalName")="Rob Nicholson"

>会话（GlobalName）=Rob Nicholson
嗨肯 - 我想到了但问题是这个变量是
需要深在一个中间层，我没想到，关于
当前会话的新内容。然而，我随后发现：
System.Web.HttpContext.Current.Session（" GlobalName"）
这意味着中间tier可以在会话缓存中获取，而不必将
传递给指向它的指针。
我假设System.Web.HttpContext.Current实际上是一个共享（静态）
属性'可用进程范围并返回HttpContext对象
用于当前正在处理的请求，这反过来又为用户提供了'自己的
会话状态。
干杯，Rob。
> Session("GlobalName")="Rob Nicholson"
Hi Ken - I thought about that but the problem was that the variable was
needed deep in a middle tier layer which, I didn''t think, new about the
current session. However, I then found:
System.Web.HttpContext.Current.Session("GlobalName ")
which means the middle tier can get at the session cache without having to
pass a pointer to it all over the place.
I assume that System.Web.HttpContext.Current is in effect a shared (static)
property that''s available process wide and returns the HttpContext object
for the current request being processed which in turn gives the user''s own
session state.
Cheers, Rob.
