This module is simple, extendible, DRY, and well-documented. The reviewer "pagenyon" has no idea what he is talking about, it does support both JSON and XML. It's a no brainer to use this and cut down on re-implementing common requests and basic auth for most RESTful APIs. 5 stars for the quality of the module and easy of use.
not very useful since it forces the use of json for all encoding
