从同一服务器上的ASP.NET MVC5控制器调用经典ASP

我正在将一个古老的经典asp项目迁移到ASP.NET，但是由于这是一件很大的老事，所以我会分块地进行。因此，我正处于需要他们共同努力的阶段。经典ASP和.NET的文件都在同一个项目中。旧的经典asp项目使用Session变量（新的.NET项目不使用），因此我尝试调用经典的ASP页来执行此操作。

这是经典的asp“桥梁”：

<!--#include virtual="/members/includes/db.config.asp" -->
<!--#include virtual="/members/includes/classes/clsLogin.asp" -->
<!--#include virtual="/members/includes/classes/clsAccess.asp" -->
<!--#include virtual="/members/includes/classes/clsUser.asp" -->
<!--#include virtual="/members/includes/classes/clsEntity.asp" -->
<!--#include virtual="/members/includes/classes/Database/clsDatabase.asp" -->
<!--#include virtual="/members/includes/classes/Helper/clsSessionVars.asp" -->
<!--#include virtual="/members/includes/classes/Helper/clsGlobal.asp" --><%'This file has global functions '%>
<%
Dim userId : userId = CStr(Request.QueryString("userId"))
Dim username : username = Cstr(Request.QueryString("username"))

Dim objAccess : Set objAccess = new clsAccess
Dim objDb : Set objDb =  new clsDatabase
Dim objUser : Set objUser = new clsUser
Dim objLogin : Set objLogin = new clsLogin
Dim objEntity : Set objEntity = new clsEntity

'Set user session etc.
if(Request.QueryString("function") = "session") then    

    Dim userRecord : Set userRecord = objUser.GetUserById(userId) 
    Dim rsEntity : Set rsEntity = objEntity.GetById(userRecord("EntityId"))
    'Login classic asp : Sets the session variables.            
    Call objLogin.LoginUser(userRecord, username, rsEntity) 

'Kill the session i.e. Log out
elseif(Request.QueryString("function") = "kill") then

    Session.Contents.RemoveAll()
    Session.Abandon()   
    Response.Write("Session Killed")

End if
%>

但是，我遇到了真正的问题，无法从.NET Controller调用它并获取存储的会话变量。我尝试了FileWebRequest：

private void SetClassicASPSessionVars(ApplicationUser user)
        {            
            try
            {
                string url = "~/members/includes/classes/aspbridge.asp" + "?function=session&userId=" + Url.Encode(user.UserId.ToString()) + "&username=" + Url.Encode(user.UserName);                
                Uri serverUri = new Uri(url);
                HttpWebRequest request = (HttpWebRequest)WebRequest.Create(serverUri);
                request.Method = "POST";

                using (HttpWebResponse response = (HttpWebResponse)request.GetResponse())
                {
                    StreamReader reader = new StreamReader(response.GetResponseStream());
                    var content = reader.ReadToEnd();
                }                      
            }

            catch (WebException we)
            {
                throw new InvalidOperationException("Error logging in user to classic asp system. User: " + user.UserId + ". Exception: " + we);
            }
        }

这仅读取文件，并且不执行脚本，因此它仅返回源代码，并且未创建会话变量。

我也尝试过HttpWebRequest：

try
            {
                string url = "/members/includes/classes/aspbridge.asp" + "?function=session&userId=" + Url.Encode(user.UserId.ToString()) + "&username=" + Url.Encode(user.UserName);                
                Uri serverUri = new Uri(url, UriKind.Absolute);
                HttpWebRequest request = (HttpWebRequest)WebRequest.Create(serverUri);
                request.Method = "POST";

                using (HttpWebResponse response = (HttpWebResponse)request.GetResponse())
                {
                    StreamReader reader = new StreamReader(response.GetResponseStream());
                    var content = reader.ReadToEnd();
                }                      
            }

            catch (WebException we)
            {
                throw new InvalidOperationException("Error logging in user to classic asp system. User: " + user.UserId + ". Exception: " + we);
            }

但是，出现错误：无效的URI：无法确定URI的格式。

有人可以为我提供一些指导，让我了解如何使.NET控制器调用经典的ASP页。

在此先感谢，Rhys
