C# 是否可以将会话从HttpWebResponse传输到浏览器？

我需要找到某种方法以下一个顺序传递会话值：

WebApp1（WebForms）->WCF->WebApp2（WebForms/浏览器）

原因是WCF服务必须在请求到达WebApp2/Browser之前验证该请求

基本上，我需要通过WCF获取HTML和会话，然后将它们传递给WebApp2中的Iframe

我有下一个代码：

WebApp1：

-Default.aspx

Public Class _Default
    Inherits Page

    Protected Sub Page_Load(ByVal sender As Object, ByVal e As EventArgs) Handles Me.Load

        Dim pUser As String = Request.QueryString("user")

        If Not String.IsNullOrEmpty(pUser) Then
            System.Web.HttpContext.Current.Session("user") = pUser
        End If

        Dim user As String = System.Web.HttpContext.Current.Session("user")

        If String.IsNullOrEmpty(user) Then
            Response.Write("sesion no iniciada")
        Else
            Dim a As String = "<a href='http://localhost:64852/About.aspx'>ir a otra pagina</a>"
            Response.Write(String.Format("{0} ha iniciado sesion {1} pagina 1", user, a))
        End If
    End Sub
End Class

-函数Utilities.Net.getHttpStream

Friend Shared Function getHttpStream(ByVal url As String, ByVal method As String, Optional ByVal request As String = "", Optional ByVal contentType As String = "") As System.IO.Stream

    url = "http://localhost:64852/Default.aspx?user=diego"
    Dim ba As Byte() = Encoding.Default.GetBytes(request)
    Dim lg As Integer = ba.Length
    Dim rq As HttpWebRequest = HttpWebRequest.Create(url)
    Dim cookies As New CookieContainer()

    With rq
        .ContentType = contentType
        .Method = method
        .Proxy = New WebProxy()
        .ContentLength = lg
        .CookieContainer = cookies
    End With

    If method <> "GET" Then
        Dim qs As Stream = rq.GetRequestStream()
        qs.Write(ba, 0, lg)
        qs.Flush()
        qs.Close()
    End If

    Dim qr As Stream

    Dim response As HttpWebResponse = rq.GetResponse()
    response.Cookies = cookies.GetCookies(rq.RequestUri)
    qr = response.GetResponseStream()

    Return qr
End Function

问题是返回纯文本（没有HTML）而没有任何会话
