Hi all,

With the fast adoption of Let's Encrypt many people are interested in
integrating it with Tomcat. A first step was to ensure that Tomcat can
directly use the PEM certificates generated by the letsencrypt/certbot
client. An important aspect of Let's Encrypt is automation, the
certificates are relatively short lived (90 days) and must be updated
automatically. AFAIK there is no easy way yet to reload a connector in
Tomcat to pick a new certificate. The administrator either has to
restart Tomcat (bad in a production environment) or do some JMX tricks
[1] (but JMX must be enabled and secured properly).

I'm wondering if it would be possible for Tomcat to monitor the
certificates/keystore files and reload the associated connectors
automatically? If there is a consensus on this feature I'd be interested
in implementing it.
