Netscape 4.7 and duplicate cookies

Question

I've got an application that works fine on IE and Netscape 6, but NS 4.7 is
          giving me a headache. I'm trying to expire the cookies that I've originally
          written with 1-year expiration date. I originally created the cookie like
          this:
          info = new Cookie("UserID", "Bob");
          info.setMaxAge(60 * 60 * 24 * 365); // One year
          info.setPath("/");
          response.addCookie(info);
          When I try to expire it using this:
          info = Utilities.getCookie(request.getCookies(), "UserID"); // Gets the
          cookie from the request structure
          if (info != null)
          info.setMaxAge(0);
          response.addCookie(info);
          it fails on Netscape (both versions); the cookie doesn't disappear, almost
          like it ignored it. When I changed it to this:
          info = Utilities.getCookie(request.getCookies(), "UserID"); // Gets
          the cookie from the request structure
          if (info != null)
          info.setValue("0");
          info.setMaxAge(3);
          response.addCookie(info);
          it works on Netscape 6 (the cookie is invalidated enough that the code works
          and will expire in a few seconds). However, on Netscape 4.7, nothing
          changes. So I did a little debugging and found that under NS 4.7, the
          request structure ends up with TWO cookies of the same name ("UserID") and
          two different values. The first being its original value and the second
          being the value I set above. Clearly, something's not right. Is it me? Is
          NS 4.7 just buggy? I'm stuck for an answer to this mystery.
          Thanks in advance for help,
          -- Andy.

Hi,
When using Micosoft's Internet Explorer web browser, version 5.0 is supported for end users only. For administrators, changes to the iPlanet Web Server Administration Server configuration can be saved only when using Internet Explorer version 5.5. with standard Encryption.
Thanx
