To enforce HTTPS with Tomcat, you can follow these steps:

1. Configure Tomcat to use SSL: First, you need to configure Tomcat to use SSL by creating a keystore and configuring the SSL connector in the server.xml file. You can generate a keystore using Java keytool or other tools like OpenSSL.
2. Enable the HTTPS connector: Update the server.xml file in the conf directory of your Tomcat installation to include a new Connector element for the HTTPS protocol. Make sure to set the port to the default HTTPS port (443) and specify the path to your keystore file and password.
3. Redirect HTTP requests to HTTPS: To enforce HTTPS, you can configure Tomcat to automatically redirect HTTP requests to HTTPS. You can do this by adding a new Valve element in the server.xml file inside the Host element:

<Valve className="org.apache.catalina.valves.RemoteIpValve"
        remoteIpHeader="x-forwarded-for"
        remoteIpProxiesHeader="x-forwarded-by"
        protocolHeader="x-forwarded-proto"
        protocolHeaderHttpsValue="https"/>

1. Update your application to use HTTPS: Finally, make sure that your web application is configured to use HTTPS by updating any hardcoded URLs in your application to use the HTTPS protocol.

By following these steps, you can enforce HTTPS with Tomcat and ensure that all connections to your web application are secure.
