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!!
