>   Although both the luke and core admin handlers set http caching to false in the response
headers** I believe the Cache-Control settings are ignored during ajax requests in certain
browsers. This can be a problem if you're refreshing admin to get the latest do count. It
can also be a problem when you compare the count of "Num Docs" on the main index page (/solr/#/CORE)
vs the count on the core admin page (/solr/#/~cores/CORE). Consider that if you first visit
the main index page, add and commit 100 docs, and then visit core admin the doc count will
be off by 100.
>   
>   If this is an issue the ajax requests can explictly set caching to false ( http://api.jquery.com/jQuery.ajax/#jQuery-ajax-settings
) ... for example, inserting 'cache: false,' after line 91 here: https://github.com/apache/lucene-solr/blob/branch_4x/solr/webapp/web/js/scripts/dashboard.js#L91
