Hoss Man updated SOLR-1765:
---------------------------
Component/s: (was: multicore)
(was: search)
Description:
When searching across multiple shards with HTTP caching enabled, the Caching
related headers (ETag, Cache-Control, Last-Modified) in the response are based
on the "index" of the coordinating solr core, and are not influenced by the
properties of the shards. For example, take the query
http://localhost:8983/solr/core1/select/?q=google&shards=localhost:8983/solr/core2,localhost:8983/solr/core3
ETag should be calculated off of core2 and core3, instead it's being calculated
from the index of core1.
This results in index modificaitons to to core2 or core3 being "invisible" to
clients which query this URL using "If-None-Match" or "If-Modified-Since" type
requests
was:
When searching across multiple shards with HTTP caching enabled, the ETag value
in the response is only using the searcher in the original request, not the
shards. For example, take the query
http://localhost:8983/solr/core1/select/?q=google&shards=localhost:8983/solr/core2,localhost:8983/solr/core3
ETag should be calculated off of core2 and core3, instead it's being calculated
from core1.
Summary: HTTP Caching related headers are incorrect for distributed
searches (was: ETag calculation is incorrect for distributed searches)
