Unless otherwise noted in the detailed descriptions, the server returns text responses with MIME type text/plain. Many request types let you specify a response type, such as text that is typically the default, javascript, xml, or json. The associated response MIME types are text/plain, text/javascript, text/xml, and text/javascript, respectively.

Unless otherwise noted, responses format the response as a set of name=value pairs.
