title: Restrict Solr data import to localhost, but allow select from any address
body: <p>I currently have 2 machines on the same local network - one with Tomcat 7 and Solr 3.5, and the other with Apache and PHP. My PHP code gets search results via solrservername:8080/solr/corename/select?..., and I update the index by manually hitting .../dataimport?...</p>
  
  <p>How can I restrict access to the dataimport URL (preferrably by only allowing it to be accessed from localhost) without affecting the select URL? To clarify, I would rather not mess with HTTPS or add HTTP authentication if possible.</p>
