Benoit Chesneau updated COUCHDB-595:
------------------------------------

    Attachment: couchdb_att_100_continue.patch

Patch that seem to fix the issue. To put attachments, CouchDB use its own functions to receive the body and don't send the expect header back. I haven't tested yet against chunked encoding.

> CouchDB does not send the "HTTP/1.1 100 CONTINUE\r\n" line in response to a request with header "Expect: 100-continue". It does do so for chunked transfer mode, so correct expect/continue behavior can be achieved by forcing chunked mode, even when the exact length of the body is known.
> mochiweb_request.erl's recv/1 method does not send the header, but stream_body/4 does.
