The server is refusing to service the request because the request-target<sup>[1](#ref-1)</sup> 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 <sup>[2](#ref-2)</sup>.

Remove markdown line limit (#52) * Removes line length limit from Status Code Markdown This will make the data easier to use when we develop the API, it needs to be consistent, arbitrary new lines (especially in text format) will be a major issue, so some sort of workaround would have to be implemented, easier to simply fix the source files. * Removes line length limit from misc.
