How to set cookies for HTTPS?

[Amit More]

Hi friends,
For HTTP, I am creating one cookie object and setting the required parameters. The code looks like below:

Cookie cookie = new Cookie("Ispace_Auth", s19);
cookie.setDomain(sCookieDomain);
cookie.setPath("/");
cookie.setMaxAge(14400);
httpservletresponse.addCookie(cookie);
Here no problem with HTTP.
But when for same code I am trying to access files through internet over HTTPS, cookie is not getting created and hence giving me further problem. But if I am using URL rewriting then I can view my site and no problem.
But I dont want to use URL rewriting and hencforth wants to create cookies.
Is there any way to set the cookies for HTTPS server? Or can you provide some help under the cookie setting in Https server?
I am using Apache-Tomcat.
Its urgent. So please help me out.
