[rabbitmq-discuss] RabbitMQ JSON-RPC via GET rather than POST

[Emile Joubert]

Hi Donovan,

Sorry for the delay in getting back to you. I can confirm that "open" is
not idempotent which means it is not permitted to be accessed via HTTP GET.

Unfortunately I don't have a good alternative suggestion. The use of a
proxy to get around the cross-domain restrictions on POST in jQuery may
work, but I can hardly recommend it as good practice.

Regards

Emile
