Force Tomcat To Redirect All HTTP Traffic To HTTPS On Dedicated Or Cloud


What does HTTPS mean?

HTTPS is a modification of the HTTP (Hyper Text Transfer Protocol) Standard, is the protocol over which data is sent between your browser and the website that you are connected to. Where, “S” stands for Secure, which means the HTTP connection is encrypted.
 

HTTPS is a secure web protocol, which is commonly used by e-commerce websites to provide secure transactions for its users.


Why is HTTPS important?

For instance, unsecured HTTP activity can be read by anyone on the same network,  such as your ISP or with the users with whom you share the same network.  Whereas, HTTPS is ensuring the privacy, security and the way of authenticating that the site you’re on is the one you are about to visit.

Let's Get Down To The Technical Part Now On Now To Force Redirect HTTP Connections To HTTPS On Tomcat Server in our Java hosting

Follow the below-given steps, for redirecting the domain from HTTP to HTTPS connection on Tomcat server.

Login to the tomcat server and go the below path.

server.xml, it will be under the /conf/server.xml

Where you can see the below code.

<Connector port="80" protocol="HTTP/1.1"
              connectionTimeout="20000"
              redirectPort="8443" />

Change it to.

<Connector port="80" protocol="HTTP/1.1"
              connectionTimeout="20000"
              redirectPort="443" />


Next, To force Tomcat to redirect and revert all requested HTTP traffic to HTTPS,

configure the `conf/web.xml` file with the below code.

Place this code very end of the file near and above the ending `</webapp>` tag:

<security-constraint>
       <web-resource-collection>
       <web-resource-name>Automatic Forward to HTTPS/SSL
       </web-resource-name>
       <url-pattern>/*</url-pattern>
       </web-resource-collection>
       <user-data-constraint>
          <transport-guarantee>CONFIDENTIAL</transport-guarantee>
       </user-data-constraint>
   </security-constraint>

<security-constraint>

Restart the Tomcat.
