How to use IHTMLDocument2 script?

[marcela24]

I want to retrieve the session cookie in the client side.
I found out a script called IHTMLDocument2 that can do exactly this.
I have one example:
Dim objDoc As IHTMLDocument2

But i have an error message: Microsoft VBScript compilation error '800a0401'
Expected end of statement
/cog_teste/smart_location.asp, line 6
Dim objDoc As MSHTML.IHTMLDocument2

And then i do it like this:
Set objDoc = Server.CreateObject("MSHTML.IHTMLDocument2&quot

And at this time i have this error message:
Server object error 'ASP 0177 : 800401f3'
Server.CreateObject Failed
/cog_teste/smart_location.asp, line 17
Invalid ProgID. For additional information specific to this message please visit the Microsoft Online Support site located at:

Does anybody know whta´s the problem with my code or how can i use this component? I think that ProgID error is when you don´t have the component installed.
