two solr instances?

[Jörg Kiegeland]

Is it possible to deploy solr.war once to Tomcat (which is on top of an 
Apache HTTP Server in my configuration) which then can manage two Solr 
indexes?

I have to make accessible two different Solr indexes (both have 
different schema.xml files) over the web. If the above architecture is 
not possible: is there any other solution?
