title: Does each and every subdirectory require its own ssl certificate?
body: <p>We plan to have an X.509 certificate for our web server which is running multiple independent web applications. Those web applications are running on the same web server but are not related to each other (accessed by <code>www.maindomain.com/sub1</code>, <code>/sub2</code> and so on). If we have a certificate issued for the main domain, in order to secure each web application using TLS, do we still need a certificate for each and every web application?</p>
