Types of status There five types of status codes, neatly arranged in five blocks of one hundred for easy recognition and with an eye on future expansion as not all slots are filled yet: 100-199: Informational Status Codes 200-299: Successful Client Requests 300-399: Redirected Client Requests 400-499: Client Request Errors 500-599: Server Errors codes. statusText Returns the status as a string, e.g. "OK" if 200 or "Not Found" for a 404. responseBody Retrieves the response entity body as an array of unsigned bytes. responseStream Returns the raw, uncoded bytes as received from the server in a binary data stream. responseText Returns the response as a string. responseXML Returns the response as an xml document object, fully parsable with standard dom methods. status Returns the status as an integer number. The most common ones are 200 for "OK" or 404 for "Not Found". See our list of all status codes. statusText Returns the status as a string, e.g. "OK" if 200 or "Not Found" for a 404.
