414 URI Too Long response status code indicates that the URI requested by the client is longer than the server is willing to interpret.
There are a few rare conditions when this might occur:
- when a client has improperly converted a
POSTrequest to a
GETrequest with long query information,
- when the client has descended into a loop of redirection (for example, 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.
