Web session parameters

Hi Ingvar,

The 1IM web application uses ASP.NET session state, so you can easily read and write session parameters using scripts or Webdesigner-embedded code.
msdn.microsoft.com/.../03sekbw5.aspx

Since session state lives on the server, the question is: Is information about the client certificate available on the server? If so, how can it be accessed?

Thanks Hanno. Well I don't really know, but I will pass the information to our partner and hopefully it will help them to move forward a bit.

cheers,
Ingvar

Got some more info from the partner after sending the above info:

"
Actually the problem is how to read server variables Because HTTP header is part of that.
I have tried several ways like examples below but what I get Is this error:
Object reference not set to an instance of an object.

Error comes already in this phase:
Dim Request As System.Web.HttpRequest = System.Web.HttpContext.Current.Request

Trying to get one item:
System.Web.HttpContext HttpContext.User.Identity.AuthenticationType
OR
Trying to get entire collection:
coll=Request.ServerVariables
"
Any idea on how to help?

kind regards,
Ingvar

We'd need the complete stack trace of the exception.

Try running it outside of WebDesigner; in an IIS-hosted application.

Below is what the partner runs and the results:

--- start---
Imports System.Text
Imports System
Imports System.Web
Imports System.Collections.Specialized.NameValueCollection
Imports System.Web.SessionState

Public Function Get_ITSHOP_HTTPHeader() As String


Dim loop1, loop2 As Integer
Dim arr1(), arr2() As String
Dim coll As System.Collections.Specialized.NameValueCollection
Dim Request As System.Web.HttpRequest = System.Web.HttpContext.Current.Request
Dim UserType As String= System.Web.HttpContext.Current.User.GetType.ToString

coll=Request.ServerVariables
arr1 = coll.AllKeys
For loop1 = 0 To arr1.GetUpperBound(0)
VID_Write2Log("c:\temp\IIS_HTTP_REQUEST.TXT", "Key: " & arr1(loop1))
arr2 = coll.GetValues(loop1) ' Get all values under this key.
For loop2 = 0 To arr2.GetUpperBound(0)
VID_Write2Log("c:\temp\IIS_HTTP_REQUEST.TXT", UserType)
Next loop2
Next loop1


Return "the end"
End Function
--end--


The result is pretty much same. The trace below is from application log under IIS

Can you open a support request for this problem please, there is not an obvious answer I'm afraid.

Thanks.

The customer have opened a support case (Service Request # 3991179). The first response was that it might take some time since it's being handed to development.
