> One of patterns in using microservices is consuming REST and producing from REST resources using REST component. For instance have a frontend exposed API using REST DSL and calling backend using REST producer.
> As most HTTP components generate URIs by concatenating {{Exchange.REST_HTTP_URI}} and {{Exchange.HTTP_PATH}} when the REST producer generates {{Exchange.REST_HTTP_URI}} header that contains the whole URI to be used it should remove the {{Exchange.HTTP_PATH}} header in order to prevent incorrect URIs.
> For example {{Exchange.HTTP_PATH}} is set by the REST consumer to {{/api/pet/123}}, and REST producer is configured with {{Exchange.REST_HTTP_URI}} with URI {{/api/pet/&#123;petId&#125;}} if the {{Exchange.HTTP_PATH}} is not removed HTTP component (IMHO all except for Restlet) would try to send the request to {{/api/pet/&#123;petId&#125;/api/pet/123}}.
