HTTP Method Transformation
==========================

Ocelot allows the user to change the HTTP request method that will be used when making a request to a downstream service.

This achieved by setting the following Route configuration:

.. code-block:: json

    {
        "DownstreamPathTemplate": "/{url}",
        "UpstreamPathTemplate": "/{url}",
        "UpstreamHttpMethod": [
            "Get"
        ],
        "DownstreamHttpMethod": "POST",
        "DownstreamScheme": "http",
        "DownstreamHostAndPorts": [
            {
                "Host": "localhost",
                "Port": 54321
            }
        ],
    }

The key property here is **DownstreamHttpMethod** which is set as POST and the Route will only match on GET as set by **UpstreamHttpMethod**.

This feature can be useful when interacting with downstream APIs that only support POST and you want to present some kind of RESTful interface.
