MERGE HTTP verb does not submit options.data in an ajax call

[neo98052]

The MERGE HTTP keyword does not currently submit the payload (options.data) in the call to the ajax method. The OData protocol uses both the PUT and MERGE keywords to enable updating of data.

The issue is on line 5256:

xhr.send(type === "POST"

type === "PUT"

type === "DELETE" ? s.data : null);

If an additional check is added for type === "MERGE", it will enable the scenario.

Odata docs suggest using POST with the .ajax method and sending the MERGE verb via the X-HTTP-Method header. Here is a link with sample jquery code:  http://social.msdn.microsoft.com/Forums/en/adodotnetdataservices/thread/e2fedabb-ed38-4b68-bb75-1fcfc9808267

OData provides this functionality in order to support clients that don't support all of the verbs. However, it requires clients to always implement the beforeSend callback in order to attach the header. As this is the only OData HTTP verb that jQuery does not support, it would be useful if it did fully support it.

MERGE is not a valid HTTP/1.1 verb, so I am not sure why jQuery should go out of its way to support it.

#6612 is a duplicate of this ticket.

Fixed in jQuery 1.4.3; GET and HEAD requests have their .data property serialized to the URL, but all other verbs send the data as the entity body.
