Hi All,
I have recently upgraded to SOLR 7.5 from SOLR 4.10.3 and
believe I have noticed a change in the way HTTP caching is operating.
I have installed the vanilla SOLR 7.5 on Windows 2012 R2
I have run the techproducts example where the solrconfig includes :
<requestDispatcher>
<httpCaching never304="true" />
</requestDispatcher>
I have opened the SOLR admin UI on IE11 and run a query (*:*) against the
techproducts core. If I re-execute exactly the same query from the UI by
re-pressing the
"execute query" button the results are exactly the same ( including the QTime
value). Running IE11 in debug mode (F12) with "Always Refresh from server"
switched OFF it
appears the http response from SOLR is 304 (use cached results).
If I change the IE11 "internet options/ temporary internet files/ check for
newer versions of stored pages" from value "Automatically" to "Every time I
visit the
webpage" then repressing the "execute query" button returns http response 200
as expected.
I was expecting the <httpCaching never304="true" /> configuration to prevent
304's being returned from SOLR - is this a mistaken assumption?
I need to ensure that a user will not get browser cached results when doing
queries from the SOLR Admin UI. I can not change the IE11 browser internet
options. Is there
a way to ensure that the server always returns the latest results and does not
allow browser caching to be used?
Many Thanks,
Guy
