+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 ReRoute configuration:
+
+.. code-block:: json
+
+    {
+        "DownstreamPathTemplate": "/{url}",
+        "UpstreamPathTemplate": "/{url}",
+        "UpstreamHttpMethod": [
+            "Get"
+        ],
+        "DownstreamHttpMethod": "POST",
+        "DownstreamScheme": "http",
+        "DownstreamHostAndPorts": [
+            {
+                "Host": "localhost",
+                "Port": 53271
+            }
+        ],
+    }
+
+The key property here is DownstreamHttpMethod which is set as POST and the ReRoute 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.
