Subject Re: Accessing Solr collections at different ports
Date Fri, 03 May 2019 15:48:46 GMT
This is not true. You can run as many separate JVMs on a single physical machine as you have
available ports. There’s no capability to address a Solr _collection_ in the _same_ JVM
by a different port though.

But what you didn’t mention is having separate collections per client. A single Solr instance
(defined by a running JVM) can host a number of different collections. So you have URLS like

Now you restrict the URLs available to client1 to collection1, client2 to collection2 etc.
