I'm asking for your advice. I would like to set up a temporary site when Tomcat and aplication are off. Unfortunately, our Tomcat turns off after apr. 4 minutes. I was thinking of setting up another Tomcat, with the temporary site. After closing the first Tomcat (with the main aplication), I could quickly open the other Tomcat, the one with the temporary site. What are you thinking about this? Do you have any other ideas? I want to avoid the 4 minutes moment, when the client sees nothing.
The usual approach to this would be to run another server in failover (or load balancing) mode. You could either use Tomcat's built-in load-balancing, or put an Apache in front of the Tomcats and have it load-balance between them (that's what I would recommend).
