Subject [jira] [Commented] (COUCHDB-1175) Improve content type negotiation for couchdb JSON responses
Date Thu, 07 Jul 2011 19:28:16 GMT

    [ https://issues.apache.org/jira/browse/COUCHDB-1175?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13061517#comment-13061517

Robert Newson commented on COUCHDB-1175:
----------------------------------------

http://www.gethifi.com/blog/browser-rest-http-accept-headers

IE sends: Accept: image/jpeg, application/x-ms-application, image/gif, application/xaml+xml,
image/pjpeg, application/x-ms-xbap, application/x-shockwave-flash, application/msword, */*

Both text/html and application/json have the same preference value (1.0). Whichever way we
jump, something goes wrong.

The point of insisting on 'Accept: application/json' exactly is that only explicit calls from
code, XHR, etc, can do it, it's unlike anything any browser sends.

I don't much *like* the solution, but I don't see a better one right now.

> Currently we ignore qvalues when negotiation between 'application/json' and 'text/plain'
when returning JSON responses.
> Specifically, we test directly for 'application/json' or 'text/plain' in the Accept header.
Different branches have different bugs, though. Trunk returns 'application/json' if 'application/json'
is present at all, even if it's less preferred than 'text/plain' when qvalues are accounted
for.
> We should follow the standard.
