+1 for adding a option for the bridge endpoint of the http consumer.
In this way we don't add such removeHeader and turn off the exception
option for the bridge endpoint.

Hi
Thanks for the findings. Can you try removing those headers, you can
use .removeHeader to get rid of them.
And create a ticket in JIRA so we can fix it in 2.1 that bridging HTTP
related endpoints works.
We may need to add some headers so Camel knows you want to bridge them
to avoid using special headers or wrap return codes etc.

Hi,
Was debugging through this issue, and below are my observations.
Lets say I am using this url (http://localhost:6666/customers/accounts) from
the client to post
1. In HttpProducer class when I inspected the Camel Exchange In Headers,
noticed both CamelHttpUri and CamelHttpPath headers having the same value.
eg: /customers/accounts
And in the protected HttpMethod createMethod(Exchange exchange) an uri is
being constructed by concatenating CamelHttpUri + CamelHttpPath, which
means in this example uri becomes /customers/accounts/customers/accounts and
this same uri is being used to construct
org.apache.commons.httpclient.HttpMethod which of course is not constructed
with the right uri and hence fields like host and all in the HttpMethod
object is not set properly, I suspect this could be the problem.
Wouldn't the camel header (CamelHttpUri ) in the exchange should have been
ideally set to http://localhost:6666, which would have resulted in the right
uri being constructed.
But wasn't sure where these camel headers are being set in the exchanges.
Does it makes any sense to any of the camel contributors ??
Cheers!!

Hi,
I have the following routes defined in my application.
from("jetty:http://0.0.0.0:6666?matchOnUriPrefix=true";)
.to("http://localhost:8899?throwExceptionOnFailure=false";);
from("jetty:http://0.0.0.0:8899?matchOnUriPrefix=true";).to("cxfbean:customerCXFService");
Basically the first endpoint (6666) is just routing/redirecting to the
second end point (8899).
When the client uses the endpoint (8899) directly, it works fine. But
when
the client uses the endpoint 6666, it has to ideally route it to 8899
and
then return the result but then it throws IllegalArgumentException host
parameter is null.
The same route configuration works fine in the 2.0 M2 release, started
choking after I upgraded to M3 release.
Any help appreciated.
Cheers!!
