For index updates and queries, you *can* access it by the
/solr/mycollection name.  Although there may be no core by that name,
the base URL will work.

Just now, I also tried /solr/mycollection/admin/system, which I expected
would NOT work because I have the collection_shardN_replicaN core names.
 On my 4.2.1 production cloud, this DOES work.  Your email had given me
the idea of filing a feature request to allow this shortcut, but it
appears that it's already a feature.  In situations where
maxShardsPerNode is used, you wouldn't be able to use that shortcut to
get all the info, but you could get most of it.

I can think of a workaround for the maxShardsPerNode limitation:  If you
access /solr/admin/cores on a machine before asking for further info,
your program will know what cores exist on that machine, so you'd be
able to get ALL info.
