The 414 (URI Too Long) status code indicates that the server is refusing to
|
|
|
|
|
service the request because the request-target ([Section 5.3 of RFC7230][2]) is
|
|
|
|
|
longer than the server is willing to interpret. This rare condition is only
|
|
|
|
|
likely to occur when a client has improperly converted a POST request to a GET
|
|
|
|
|
request with long query information, when the client has descended into a "black
|
|
|
|
|
hole" of redirection (e.g., a redirected URI prefix that points to a suffix of
|
|
|
|
|
itself) or when the server is under attack by a client attempting to exploit
|
|
|
|
|
potential security holes.
|
|
|
|
|
|
|
|
|
|
A 414 response is cacheable by default; i.e., unless otherwise indicated by the
|
|
|
|
|
method definition or explicit cache controls
|
|
|
|
|
(see [Section 4.2.2 of RFC7234][3]).
