application_authenticaterequest

和是的每个请求本身都是独一无二的。从服务器的角度来看，你说这个用户属于这个用户的唯一方式是

a。会话ID

b。基于认证的校长

我假设您正在谈论这样做以及身份验证。这里

就是我所做的，而且效果很好。这取自

MSDN上的一个例子。
http://msdn.microsoft.com/library/de...SecNetHT04.asp

''在global.asax

Sub Application_AuthenticateRequest（ByVal发送者为对象，ByVal e As

EventArgs）

''尝试验证用户时触发


''提取表单身份验证cookie

Dim cookieName As String = FormsAuthentication.FormsCookieName

Dim authCookie As HttpCookie = Context.Request.Cookies（cookieName）


如果authCookie什么都没有那么

''没有认证cookie。

返回

结束如果


Dim authTicket As FormsAuthenticationTicket


尝试

authTicket = FormsAuthentication.Decrypt（authCookie.Value）

Catch ex As Exception

''记录异常详情（为简单起见省略）

返回

结束尝试


如果authTicket是什么都没有

''Cookie无法解密。

返回

结束如果


昏暗的角色（）As String = {" role1"，" role2"，" role3"}


''创建一个Identity对象

Dim id As FormsIdentity = New FormsIdentity（authTicket）


''此委托人将在整个请求中流动。

Dim principal As GenericPrincipal = New GenericPrincipal（id，roles）

''将新的主体对象附加到当前的HttpContext对象

Context.User = principal

End Sub


Private Sub Page_Load（ByVal sender As System.Object，ByVal e As

System.EventArgs）处理MyBase.Load

''放置用户代码初始化这里的页面

Dim p As System.Security.Principal.IPrincipal =

HttpC ontext.Current.User


''用户名

Response.Write（"您的用户名" &安培; p.Identity.Name）


如果p.IsInRole（" role1"）那么

Response.Write（" User is in role1"）

否则

Response.Write（用户不在role1中）

结束如果

结束Sub

and yes each request is a unique by itself. the only way you say that it
belong to this user from a server''s prespective is
a. session id
b. principal based on authentication

I assume you are talking about doing this along with authentication. Here
is what I''ve done, and it works great. This was taken from an example on
MSDN.
http://msdn.microsoft.com/library/de...SecNetHT04.asp

''in global.asax
Sub Application_AuthenticateRequest(ByVal sender As Object, ByVal e As
EventArgs)
'' Fires upon attempting to authenticate the user

''Extract the forms authentication cookie
Dim cookieName As String = FormsAuthentication.FormsCookieName
Dim authCookie As HttpCookie = Context.Request.Cookies(cookieName)

If authCookie Is Nothing Then
''There is no authentication cookie.
Return
End If

Dim authTicket As FormsAuthenticationTicket

Try
authTicket = FormsAuthentication.Decrypt(authCookie.Value)
Catch ex As Exception
'' Log exception details (omitted for simplicity)
Return
End Try

If authTicket Is Nothing Then
'' Cookie failed to decrypt.
Return
End If

Dim roles() As String = {"role1","role2","role3"}

'' Create an Identity object
Dim id As FormsIdentity = New FormsIdentity(authTicket)

'' This principal will flow throughout the request.
Dim principal As GenericPrincipal = New GenericPrincipal(id, roles)
'' Attach the new principal object to the current HttpContext object
Context.User = principal
End Sub

Private Sub Page_Load(ByVal sender As System.Object, ByVal e As
System.EventArgs) Handles MyBase.Load
''Put user code to initialize the page here
Dim p As System.Security.Principal.IPrincipal =
HttpContext.Current.User

''username
Response.Write ("Your username " & p.Identity.Name)

If p.IsInRole("role1") Then
Response.Write("User is in role1")
Else
Response.Write("User is not in role1")
End If
End Sub
