I have two Web server instances (iPlanet 4.1). One is secure and the other is not. The secure site is for user logon and the non-secure site contains a product catalogue. When a user logon to the secure site and click on the shopping button, he will be redirected to the non-secure site where a session is automatically created there. This works fine in Netscape browser. The user can switch between browsing the catalogue and also his logon pages. But it has a problem in Internet Explorer. Once a new session is created on the non-secure site, the session on the secure site is gone. How can I make the solution work on both browser?
