That sounds like a plan. I love peer-reviews... :-)

> 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)
