However, the docid and rev that are part of every document > would make it extremely easy to instead generate solid Etag headers, and > then return 204 Not Modified responses for GET and HEAD requests if the > client sends along the most current Etag value. > For example, instead of: > HTTP/1.1 200 OK > Server: inets/develop > Date: Sat, 15 Sep 2007 11:21:41 GMT > Cache-Control: no-cache > Pragma: no-cache > Expires: Sat, 15 Sep 2007 11:21:41 GMT > CouchDB should return something like: > HTTP/1.1 200 OK > Server: inets/develop > Date: Sat, 15 Sep 2007 11:21:41 GMT > Cache-Control: must-revalidate > Etag: ${docid}@${rev} > Sufficiently sophisticated clients (such as Python httplib2) could then use > If-None-Match to perform conditional GET requests. > Thinking about it again, as the docid is already in the URL, only the rev > is needed in the Etag headers. > -- > Comment 1 by cml...@gmx.de, Oct 01, 2007 > See also http://intertwingly.net/blog/2007/09/24/Tests-Id-Like-CouchDB-to-Pass#etag -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online.
