Thomas Peuss updated SOLR-127:
------------------------------
Attachment: HTTPCaching.patch
Updated patch inspired by Hoss Mans comments.
Changes:
* Cache header settings can now be set per request handler. Omitting the
parameters switches off cache header generation (fall back to old behaviour).
** <int name="httpCacheLivetime">0</int>: Set "freshness" timespan in seconds
** <bool name="httpCacheForceRevalidation">true</bool>: controls if we emit
"must-revalidate"
** <bool name="httpCacheForcePrivate">false</bool>: constrols if we emit
"private"
* Some refactoring to make the Filter class smaller
* Updated testcase to check that we do not emit cache headers on POST requests.
> Make Solr more friendly to external HTTP caches

> an offhand comment I saw recently reminded me of something that really bugged
> me about the serach solution i used *before* Solr -- it didn't play nicely
> with HTTP caches that might be sitting in front of it.
> at the moment, Solr doesn't put in particularly usefull info in the HTTP
> Response headers to aid in caching (ie: Last-Modified), responds to all HEAD
> requests with a 400, and doesn't do anything special with If-Modified-Since.
> t the very least, we can set a Last-Modified based on when the current
> IndexReder was open (if not the Date on the IndexReader) and use the same
> info to determing how to respond to If-Modified-Since requests.
> (for the record, i think the reason this hasn't occured to me in the 2+ years
> i've been using Solr, is because with the internal caching, i've yet to need
> to put a proxy cache in front of Solr)
