Response.Redirect in a COM+ Object Called from Classic ASP Page

Question

Basically we moved from IIS 5 to IIS 7 and I am trying to update some of our old COM objects to .NET by rewriting them in C#. What I am have so far is a Classic ASP page calling the COM+ object and then I am trying to do a simple redirect within the COM+ object (this is just for testing purposes, it's not what the object will do eventually).

My problem/question is, why does the redirect call not work properly? Am I doing something wrong or can you not redirect within a COM+ object? All that happens is a blank white page comes up and if I check the IIS logs, I see no errors.

Here is my code so far:
In Classic ASP (the call to COM+)

Set oBankReg = CreateObject("BVSRegistration.SignIn")  
oBankReg.GetBankId(bankid)

Code in C# COM object:

using System;  
using System.Web;  
using System.Text;  
using System.EnterpriseServices;  
using System.Collections.Generic;  
using System.Runtime.InteropServices;  

[assembly: ApplicationName("BVSRegistration")]  
[assembly: Description("COM+ upgrade of the BVSRegistration VB6 SignIn.cls.")]  
[assembly: ApplicationActivation(ActivationOption.Server)]  
[assembly: ApplicationAccessControl(false, AccessChecksLevel = AccessChecksLevelOption.ApplicationComponent)]  

namespace BVSRegistration  
{   
    public class SignIn : ServicedComponent       
    {    
        public void GetBankId(string bankid)  
        {  
            HttpContext.Current.Response.Redirect("http://www.google.com");  
        }  
    }  
}  

Any ideas? Thanks

Answer 1

ASP.Net's Response.Redirect uses the ASP.Net stack, which is not in use in an ASP page.

You need to either switch away from ASP or call ASP's Response.Redirect.

HttpContext will only be set in the context of an ASP.NET setting. Since you are calling from ASP classic, it won't be bound to the actual request/response stream.

What you should do is indicate whether or not to redirect from your COM+ object, and call classic ASP's equivalent to Redirect.
