ssl - Force Tomcat to redirect to HTTPS without changing web.xml security constraints -

I already know how to configure Tomcat so that it redirects the HTTP request to HTTPS:

1. Enable and configure SSL connector
2. Set the correct "redirectPort" attribute on a non-SSL connector
3. Modify the web.xml and select "Transport-Guarantee "To" confidential "

   My question is, what is the web? Is there a way to get the same result without modifying the XML file ?

   I'm looking for a solution where I do not have to change the web app, which has been positioned as a war file. Changes like adding a sublet filter or implementing redirects within the web application are not an option.

   Thanks for any help! Consider implementing custom tomac for redirecting

   . It's a good start.
