CXF rest service route copies all request headers to response

Hi, 

I'm having an issue where all my request headers (and all headers I add
during the route) are being copied to my http response (camel 2.12.0).

My CXF service bean looks like this:
@Path("/equipment/health/summaries")
public class EquipmentHealthSummaryWebService {
...
	@Path("/stations/{stationId}")
	@GET
	@Produces({"application/json", "application/xml"})
	@Profiled(tag="web.getEquipmentGroupHealthSummaries", level="WARN")
	public EquipmentGroupHealthSummaries
getEquipmentGroupHealthSummaries(@PathParam("stationId") String stationId) {
		return null;
	}
...

My configured endpoint looks like this:
	<cxf:rsServer id="rsEquipmentHealthRecordsWebService" address="/" 
		loggingFeatureEnabled="true">
		<cxf:serviceBeans>
			<ref bean="equipmentHealthRecordWebService"/>
			<ref bean="equipmentHealthSummaryWebService"/>
			<ref bean="equipmentGroupWebService"/>
		</cxf:serviceBeans>
		<cxf:providers>
			<ref bean="jsonProvider"/>
		</cxf:providers>
	</cxf:rsServer>
    
Finally my route looks like this:
	
from("cxfrs://bean://rsEquipmentHealthRecordsWebService?bindingStyle=SimpleConsumer")
			.tracing()
			.setHeader("user").mvel("org.apache.shiro.SecurityUtils.getSubject()")
			.recipientList(simple("direct:${header.operationName}"));

and
		from("direct:getEquipmentGroupHealthSummaries")
			.beanRef("equipmentGroupService", "getEquipmentGroupHealthSummaries")

When I hit this service, every header in my request gets copied to my
response. How can I prevent this?

Thanks

John

Hi

IMHO the way headers are dealt with by default by CXFRS is 
confusing/wrong, hopefully a filter strategy (as already recommended) 
will help, in meantime, can you please consider attaching a Maven-based 
test project to

https://issues.apache.org/jira/browse/CAMEL-6865 ?

so that we can investigate if it is realistic to update the current 
default header filter strategy ?

Thanks, Sergey

set a headerFilterStrategy on the http component and write your own filter to remove the headers 
you don't want.

Documented here under "HttpEndpointOptions":

As an extra detail, I also have the following route for a different endpoint:

		from("direct:getEquipmentHealthRecords")
			.beanRef("equipmentEinService")
		
.split().simple("body").parallelProcessing().aggregationStrategyRef("equipmentHealthRecordsAggregationStrategy")
				.beanRef("equipmentHealthRecordService")
				.beanRef("healthRecordSecurityFilter",
"filterEquipmentHealthRecord(${header.user}, ${body})")
			.end();

and the headers do not get copied to the response here. I'm guessing the
split/aggregation is losing them which is good for me, but how do can I
consistently make sure my response does not get a copy of my request
headers?
