Config Variables

Config variables have the effect of changing global "behavior" and are identified by a leading underscore, for example: _url.

Anything set this way will apply to all requests, unless you over-ride them. Any other variables will be treated as normal global variables.

Name	Type	Effect
_url	string	Default "base URL" for all requests
_headers	json	Sets headers for all requests
_cookies	json	Sets cookies for all requests
_ssl	boolean / json	Set this to (true) if you have to test HTTPS and the server is strict
_charset	string	Set this to (null) if you want to not append ; charset=UTF-8 to the Content-Type header
_followRedirects	boolean	Set this to (false) to not follow redirects by default
_connectTimeout	number	Increase the connect timeout which defaults to (30000) (30 seconds)
_readTimeout	number	Increase the read timeout which defaults to (30000) (30 seconds)
_proxy	string / json	The URI of the proxy server to use

For more details, you can also refer to the corresponding configure keys in the Karate engine that is used behind the scenes.

Those that expect a JSON can also be a JS function that returns a JSON, allowing for some very dynamic behavior.
