The HTTP 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 {{HTTPMethod("POST")}} request to a {{HTTPMethod("GET")}} request 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.
