What makes PerimeterX challenge different

Where the PerimeterX challenge parameters come from

website_urlRequired: The exact page where this challenge appears, including the relevant path rather than only the site home page.
proxyRequired: The proxy for the solve session; when a result is network-bound, use the same exit for the subsequent target request.
user_agentOptional: The browser user agent for this challenge session; keep it consistent when the returned result is bound to that session.
website_keyOptional: The public site or widget key copied from this exact target integration; it is not a secret key.
