> 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
