BMP HTTP Response Codes

Our first pass at assigning response codes to conditions used only standard codes. However, in some cases this stretched or even ignore the original purpose for the codes in question. Thus, we are switching to a better scheme as time permits.

HTTP Standard Codes

RFC2295, RFC2324, RFC2616, RFC2518, RFC2774, RFC2817, RFC3229, RFC3648, RFC4918

http://www.iana.org/assignments/http-status-codes

Below is a table of the codes currently specified by RFCs and the registry.

1xx	10x 12x	Informational
2xx	20x 22x	Successful
3xx	30x	Redirection
4xx	40x 41x 42x 44x 490x 49x	Client Error
5xx	50x 51x	Server Error

Blink HTTP Response Codes

Given the above ranges of official and semi-official codes, our Server Errors will start in the range 56x and our Client Errors will start in the range 46x. Unless it is clear that our usage is standards-compliant, we will avoid reusing existing codes.

BlinkForms2 Submission errors will start in the 47x range for Client Errors and 57x range for Server Errors

Below is a table of the codes that will be used by Blink’s internal AJAX services.

200	OK; body = content
204	No Content; no body The request was successful but there is no data to be returned.
304	Not Modified; no body The requested resource has not been modified since it was last requested.
400	Bad Request; body = description of request syntax error The client should not repeat the request without modification.
464	Not Found; body = description of missing item The item specified in the request could not be found.
470	Form Failed Validation; body = JSON { “errors”: { “field”: “error on field”, ... }, “message”: “display text” } The form record submitted does not pass validation.
471	Form Custom Error; body = JSON { “errors”: { “field”: “error on field”, ... }, “message”: “display text” } The form record submitted does not pass validation by the third-party service.
500	Internal Server Error; body = description of server error An unexpected condition prevents the request from being fulfilled.
563	Illegal Interaction; body = description of server error Selected Interaction contains unsafe or restricted code.
