Subject Re: Is anyone using proxy caching in front of solr?
Date Thu, 21 Feb 2019 07:52:39 GMT
Hi Joakim,

I suggest you to read these resources:

http://lucene.472066.n3.nabble.com/Varnish-td4072057.html
http://lucene.472066.n3.nabble.com/SolrJ-HTTP-caching-td490063.html
https://wiki.apache.org/solr/SolrAndHTTPCaches

which gives information about HTTP Caching including Varnish Cache,
Last-Modified, ETag, Expires, Cache-Control headers.

Kind Regards,
Furkan KAMACI
