Field Summary

static int	ACCEPTED Servers should issue this status code if the view-window request was acceptable, but a subsequent view-window request was found in the queue which consequently superseded the request (because wait=no).
static int	BAD_REQUEST Servers should issue this status code if the request is incorrectly formatted, or contains an unrecognized field in the query string.
static int	NOT_FOUND This status code should be issued if the server cannot reconcile the requested resource with an issued Target ID.
static int	NOT_IMPLEMENTED This status code may be used if a portion of this Recommendation | International Standard that is required by the request cannot be serviced.
static int	OK The server should use this status code if it accepts the view-window request for processing, possibly with some modifications to the requested view-window, as indicated by additional headers included in the reply
static int	SERVICE_UNAVAILABLE This status code should be used if a channel id specified in the Channel ID request field is invalid.

Field Detail

Constant Field Values

ACCEPTED

static final int ACCEPTED

Servers should issue this status code if the view-window request was acceptable, but a subsequent view-window request was found in the queue which consequently superseded the request (because wait=no). When the first request becomes irrelevant before the server is able to process and commence transmission of a response, then the 202 status code shall be used. This is a common occurrence in practice, since an interactive user may change his/her region of interest multiple times before the server finishes responding to an earlier request, or before the server is prepared to interrupt ongoing processing.

BAD_REQUEST

static final int BAD_REQUEST

Servers should issue this status code if the request is incorrectly formatted, or contains an unrecognized field in the query string.

NOT_FOUND

static final int NOT_FOUND

This status code should be issued if the server cannot reconcile the requested resource with an issued Target ID. This may result from unauthorized access attempts or, more likely, from a time limit expiring. If the client misses this time window, due to a poor connection, it may find that the Target ID is no longer active.
