Parameters

Name	Type	Description	Default Value	Required
Name	String	The name of this configuration. With this name can be later referenced.		x
Connection	Request	The connection types that can be provided to this configuration.		x
Base Path	String	Base path to use for all requests that reference this config.	/
Follow Redirects	Boolean	Specifies whether to follow redirects or not. Default value is true.	true
Send Body Mode	Enumeration, one of: ALWAYS AUTO NEVER	Defines if the request should contain a body or not. If AUTO, it will depend on the method (GET, HEAD and OPTIONS will not send a body).	AUTO
Request Streaming Mode	Enumeration, one of: AUTO ALWAYS NEVER	Defines if the request should be sent using streaming or not. If this attribute is not present, the behavior will depend on the type of the payload (it will stream only for InputStream). If set to true, it will always stream. If set to false, it will never stream. As streaming is done the request will be sent user Transfer-Encoding: chunked.	AUTO
Enable Cookies	Boolean	If true, cookies received in HTTP responses will be stored, and sent in subsequent HTTP requests.	true
Response Timeout	Number	Maximum time that the request element will block the execution of the flow waiting for the HTTP response. If this value is not present, the default response timeout from the Mule configuration will be used.
