Kind times, Juan!
Thanks for your explanations!
In my case does not suppose to change wiki from external, if that may
say. I have two VMs with jspwiki and frontend nginx (with load balance
configuration) for reliability in cases when one instance will be
stopped. People which changes wiki pages do it on one of instance and my
problem is nothing changes on second without reload corresponding tomcat
context.
I will try implement first variant from your suggestions. Any additional
information or ideas greatly appreciated.
