Marcello Nuccio commented on COUCHDB-941:
-----------------------------------------
I add it here since I think it is non obvious:
The workaround is be sure to specify ?limit=1
or some similarly restrictive query.
> Make CouchDB benefit more from ETag caching

> Key: COUCHDB-941
> URL: https://issues.apache.org/jira/browse/COUCHDB-941
> Project: CouchDB
> Issue Type: Improvement
> Components: Database Core
> Affects Versions: 1.0.1
> Reporter: Randall Leeds
> Original Estimate: 504h
> Remaining Estimate: 504h

> Right now couch_httpd processes HEAD requests as a GET and leaves it to
> MochiWeb to drop the response body. It would be good if some ETag metadata
> could be passed through the code such that we avoid disk operations when the
> ETag matches.
