url = "http://domain/remote.asp"
set xmlhttp = Server.CreateObject("MSXML2.ServerXMLHTTP")
xmlhttp.open "GET", url, false
xmlhttp.send ""
Response.write xmlhttp.responseText
set xmlhttp = nothing

*remote.asp*
bLogin = Session("login")
sUserName = Request.Cookies("username")
Response.Write(nUserID & " " & sUserName)

How can the remote page be in session, if it is on a different server as
the local.asp page, as a second session cookie and username cookie can not
be set then for the right domain?

On second thought, those cookies would have to exist on the server!

That will not do.

Hi,

thanks for your reply. The two asp pages are on different servers. what I
try to do is automatic login. eg., user A has logged in at Server A. some
links on web pages of server A point to server B. so when server B detected
a visitor is coming from server A, it will check if the user has logged in
Server A. if logged in, then set the user also logged in Server B.

What I thought before is remote.asp is executed on Server B, so it can
retrive session and cookies through it. but the fact has proved I'm wrong.
I'm wondring is it possible to retrieve sessions and cookies of a remote
server?

thanks.

A "session" in the ASP sense needs a cookie that is kept on the
client/browser and defines the session. Session variables reside on the
server, but are only available to pagest that show the session cookie.

So if you fetch a page of another server on a server
[by asp code Server.CreateObject("MSXML2.ServerXMLHTTP")],
the session cookie should be on that server too without
any browser on that server. That seems impossible under ASP.
