Message Body

Camel will store the HTTP response from the external server on the OUT body. All headers from the IN message will be copied to the OUT message, so headers are preserved during routing. Additionally Camel will add the HTTP response headers as well to the OUT message headers.

Response code

HttpOperationFailedException

Calling using GET or POST

The following algorithm is used to determine whether the GET or POST HTTP method should be used:
1. Use method provided in header.
2. GET if query string is provided in header.
3. GET if endpoint is configured wi th a query string.
4. POST if there is data to send (body is not null).
5. GET otherwise.
