Based on my > research, the patch SOLR-4470 (Security for inter-solr-node requests) would > be ideal for resolving these issues (please refer to the address: > https://wiki.apache.org/solr/SolrSecurity#Security_for_inter-solr-node_requests). > However, it seems to me that these security patches are out-of-box additions > to the current Solr source codebase, which don't seem to be available in the > recent Solr releases. > > If someone could point out which Solr releases or the jars from some online > repositories that contain this patch, it would be appreciated very much. > > Jerry > > > This e-mail is confidential.
