Subject [jira] Created: (COUCHDB-265) HEAD requests get a Content-Length header
Date Mon, 23 Feb 2009 21:20:02 GMT
HEAD requests get a Content-Length header

                 Key: COUCHDB-265
             Project: CouchDB
          Issue Type: Bug
          Components: HTTP Interface
    Affects Versions: 0.9
         Environment: curl + trunk
            Reporter: Paul Joseph Davis

Looks like HEAD requests are returning a bogus Content-Length header. If I remember my HTTP
spec correctly, HEAD requests are supposed to return no Content-Length or a Content-Length
of 0 but I could be wrong on that. Either way, it confuses the crap out of curl:

$ curl -X HEAD -i
HTTP/1.1 200 OK
Server: CouchDB/0.9.0a (Erlang OTP/R12B)
Date: Mon, 23 Feb 2009 20:56:55 GMT
Content-Type: text/plain;charset=utf-8
Content-Length: 40
Cache-Control: must-revalidate

curl: (18) transfer closed with 40 bytes remaining to read

Also, I just happened to be reading couch_http.erl the other day and I remember seeing a note
that said mochiweb automatically strips bodies so internally HEAD requests are treated like
a GET and mochiweb I guess just doesn't send a body. That's probably important.
