Subject [jira] [Commented] (COUCHDB-941) Make CouchDB benefit more from ETag caching
Date Thu, 23 Jun 2011 08:49:49 GMT

    [ https://issues.apache.org/jira/browse/COUCHDB-941?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13053719#comment-13053719

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.

> 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.
