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. |
