414

URI Too Long

The client makes a request at a certain URI, but the lengh of the URI is longer than the server is willing to interpret. This would result in the server rejecting the request with a 414 code, indicating the URI is too long.

Use Case

A malicious user is trying to exploit some security holes in a server. He tries to send in a request with an extremely large length, which may cause the server to take a very long time to interpret, possibly disrupting services to other users. But if the server has limits for the URL length, it will reject the request with a 414 code.
