Overview - HTTP Status Codes

This is a list of all the possible HTTP status codes returned by the nginx anf upload servers, along with a bried explanation of what they mean:

`http://.ngbuilds.io/`

307 (Temporary Redirect): All non-HTTPS requests. 308 (Permanent Redirect) would be more appropriate, but is not supported by all agents (e.g. cURL).

200 (OK): File was found or URL was rewritten to /index.html (i.e. all paths that have no . in final segment).
403 (Forbidden): Trying to access a sub-directory.
404 (Not Found): File not found.

201 (Created): Build deployed successfully and is publicly available.
202 (Accepted): Build not automatically verifiable. Stored for later deployment (after re-verification).
400 (Bad Request): No payload.
401 (Unauthorized): No AUTHORIZATION header.
403 (Forbidden): Unable to verify build (e.g. invalid JWT token, or unable to talk to 3rd-party APIs, etc).
405 (Method Not Allowed): Request method other than POST.
409 (Conflict): Request to overwrite existing directory (e.g. deploy existing build or change PR visibility when the destination directory does already exist).
413 (Payload Too Large): Payload larger than size specified in AIO_UPLOAD_MAX_SIZE.

200 (OK): The server is healthy (i.e. up and running and processing requests).

200 (OK): Request processed successfully. Processing may or may not have resulted in further actions.
400 (Bad Request): No payload or no number field in payload.
405 (Method Not Allowed): Request method other than POST.
409 (Conflict): Request to overwrite existing directory (i.e. directories for both visibilities exist). (Normally, this should not happen.)

404 (Not Found): Request not matched by the above rules.
500 (Internal Server Error): Error while processing a request matched by the above rules.
