问题：在通过httpwebrequest调用时，在response.redirect之后的新会话 [英] Problem: new session after response.redirect when calling via httpwebrequest

问题描述

当我设置会话值然后重定向到另一个页面时，我能够检索会话值。如下：



test-set.aspx

When I set a session value then redirect to another page I am able to retrieve the session value. As follows:

test-set.aspx

Private Sub Page_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
    Session("test") = "hello world!"
    Response.Redirect("test-get.aspx")
End Sub

test -get.aspx

test-get.aspx

Private Sub Page_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
    Response.Write("test = " & CType(Session("test"), String))
End Sub

以上结果：

The above results:

test = hello world!

但是，当通过HTTPWebRequest尝试此操作时，会创建一个新会话对于重定向的页面。

However, when trying this via a HTTPWebRequest a new session is created for the redirected page.

Private Sub Page_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
    Dim TestRequest As Net.HttpWebRequest = CType(System.Net.WebRequest.Create(Me.Request.Url.GetLeftPart(UriPartial.Authority) & "/test-set.aspx"), Net.HttpWebRequest)
    TestRequest.Method = "GET"
    Using TestResponse As Net.HttpWebResponse = CType(TestRequest.GetResponse, Net.HttpWebResponse)
        Using Reader As IO.StreamReader = New IO.StreamReader(TestResponse.GetResponseStream)
            Response.Write(Reader.ReadToEnd)
        End Using
    End Using
End Sub

使用HTTPWebRequest结果：

Using HTTPWebRequest results as:

test = 

因此HTTPWebRequest从重定向页面检索输出，但重定向页面在新会话中打开。



如何打开重定向页面它被重定向的同一个会话？



我尝试了什么：

So the HTTPWebRequest retrieve the output from the redirected page but the redirected page is opened in a new session.

How can I open the redirected page in the same session it was redirected from?

What I have tried:

HttpWebRequest.AllowAutoRedirect

HttpWebRequest.MaximumAutomaticRedirections

HttpWebRequest.KeepAlive

HttpWebRequest.UseDefaultCredentials

Response.Redirect("test-get.aspx, True")

Response.Redirect("test-get.aspx, False")

推荐答案

作为 F-ES网站注释中提到的核心，我不得不添加会话ID。这只是在GetResponse之前用一行代码完成的：

As F-ES Sitecore mentioned in the comment, I had to add the session ID. This was simply done with one line of code before GetResponse:

TestRequest.CookieContainer = New Net.CookieContainer()

因此更新后的请求如下：

So the updated request looks like:

Private Sub Page_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
    Dim TestRequest As Net.HttpWebRequest = CType(System.Net.WebRequest.Create(Me.Request.Url.GetLeftPart(UriPartial.Authority) & "/test-set.aspx"), Net.HttpWebRequest)
    TestRequest.Method = "GET"
    TestRequest.CookieContainer = New Net.CookieContainer()
    Using TestResponse As Net.HttpWebResponse = CType(TestRequest.GetResponse, Net.HttpWebResponse)
        Using Reader As IO.StreamReader = New IO.StreamReader(TestResponse.GetResponseStream)
            Response.Write(Reader.ReadToEnd)
        End Using
    End Using
End Sub
