Problem redirecting to HTTPS from jsp Links

I have an application running on 9i Application Server in HTTPS mode and working on migration to 10g Application Server.

The problem:

HTTPS has beeen configured on the 10g AS and a virtual host name (<VirtualHost-Name>). so when i access my application using a URL, https://<VirtualHost-Name>/login.jsp i can see the login page. On logging in the application uns perfectly fine. The application has few links. On clicking these links, the page is redirected to other jsps. This is done by using response.sendRedirect(/<context-name>/NextPage.jsp). Now once we have logged on, i can see the https URL in the address bar of IE. but once i click the link, it is redirected to http and the URL in IE address bar is http://<serverName>:<port>/<context-name>/NextPage.jsp. This redirection fails as a timeout. I cannot figure out why is the click on link redirecting to http URL with server-name and port. Some of the questions i have:

1. How can i make the page redirect to https. Also, the page should be redirected using the VirtualHost-Name.
2. Why is the <VirtualHost-Name> is being changed to <serverName:><port>

Thanks for help. Regards...

Any idea people?

Cheers..
