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. On Thu, Aug 20, 2009 at 6:30 PM, Srivatsa Katta<[email protected]> wrote: > > 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.
