Due to security reasons, some corporate firewalls (HTTP proxies) support only the POST and GET methods. This restriction forces a REST API client to use only those HTTP methods that are allowed through the firewall. RESTful web API implementations can work around this restriction by letting the client override the HTTP method via the custom X-HTTP-Method-Override HTTP header.

When the server gets the request, the server replaces the POST method call with the method string value set for X-HTTP-Method-Override.
