Camel uses the same message headers as the Camel Component: HTTP4 component. It also uses (Exchange.HTTP_CHUNKED,CamelHttpChunked) header to turn on or turn off the chunked encoding on the camel-jetty consumer.
Camel also populates all request.parameter and
request.headers. For example, given a client request with the URL,
http://myserver/myserver?orderid=123 , the exchange will contain a header named
orderid with the value 123.
You can get the request.parameter from the message header not only from Get Method, but also other HTTP methods.
