I ran the Ping on my demo Solr: http://chorus.dev.o19s.com:8983/solr/ecommerce_shard1_replica_n1/admin/ping?_=1634559138122&ts=1634559138122&wt=json <http://chorus.dev.o19s.com:8983/solr/ecommerce_shard1_replica_n1/admin/ping?_=1634559138122&ts=1634559138122&wt=json>
And I don’t see handler being returned.. Maybe at one time it was used? I searched in the source, and I found a DumpRequestHandler which is minimally documented in the Ref Guide and includes the echoHandler parameter: https://solr.apache.org/guide/8_9/implicit-requesthandlers.html#handlers-for-configuration <https://solr.apache.org/guide/8_9/implicit-requesthandlers.html#handlers-for-configuration> Which makes me wonder, how does one use the DumpRequestHandler? Is there a good debugging tool or other use case that I’ve been missing all these years that everyone else knows but me ;-) Sometimes I find hidden gems in Solr, and sometimes they are features that have outlived their usefulness and maybe candidates for deprecation?
