SSL for specific pages/url-patterns in tomcat

I recently configured tomcat 6 with SSL and client authentication, but the only way I could do it was modifying server configuration files (web.xml, server.xml). But as I don't have full control over the deployment server, I would like to configure everything just for some pages or url-patterns of my application without modifying the main configuration files.

For example: Main server:

• Application1 -> HTTP
• Application2 -> HTTP
• MyApplication -> HTTPS

If somebody knows how to do it, please tell me.
