Pega Service, Connecor

When the session state in a service package is set to Stateful, the service returns a cookie in the response with the Set-Cookie HTTP header. The cookie contains the Requestor ID of the requestor that processed the first request, with the prefix "PegaRULES." For another request to access the same session data, the external application must include the PegaRULES cookie in the header of that request. 

Subsequent request

It works even if the UserIdentifier and Passwrod not passed to the API. It works by the sticky session

If the content-type header of the REST response returned from the REST endpoint indicates that the response message body does not contain text, the system handles the message as an array of bytes rather than as an array of characters. To map an array of bytes, complete the following steps:

1. In the Message data section, in the Map to field, select Clipboard.
2. In the Map to key field, enter one of the following values:

• Text property: The system converts the text property to Base64-encoded text before writing it to the clipboard.
• Java object property: The system converts the java object property to a java byte array before writing it to the clipboard.
