You can only produce to endpoints generated by the HTTP component. Therefore it should never be used aas input into your camel Routes. To bind/expose an HTTP endpoint via an http server as input to a camel route, you can use the Jetty Component

GET or POST

In Camel 1.5 the following algorithm is used to determine if either GET or POST http method should be used:
1. Use method provided in header
2. GET is query string is provided in header
3. GET if endpoint is configured with a query string
4. POST if there is data to send (body is not null)
5. GET otherwise

URI Parameters

The http producer supports URI parameters to be sent to the HTTP server. The URI parameters can either be set directly on the endpoint URI or as a header with the key HttpProducer.QUERY on the message. See samples below.

...

// we query for Camel at the Google page
template.sendBody("http://www.google.com/search?q=Camel", ""null);

URI Parameters from the Message

Map headers = new HashMap();
headers.put(HttpProducer.QUERY, "q=Camel&lr=lang_en");
// we query for Camel and englishEnglish language at Google
template.sendBody("http://www.google.com/search", ""null, headers);

In the header value above notice that it should not be prefixed with ? and you can separate parameters as usual with the & char.
