Query Requests with Large Inputs

While HTTP doesn't impose any limit on the length of a URI, some implementation of server or client might have difficulties handling long URIs (usually URIs with many or large query parameters).

Every endpoint with such a URI MUST use the HTTP POST Request Method and send the query string in HTTP Request Message body using the application/x-www-form-urlencoded media type.


POST /orders HTTP/1.1
Content-Type: application/x-www-form-urlencoded


NOTE: Since this operation is safe and idempotent, using the POST method violates the HTTP protocol semantics and results in loss of cache-ability.
