Hi Thierry- After switching to the HttpClient extension, the problem POST now works. The service we're posting to is a sort of openID sign-in aggregation service called rpxnow.com . (Basically they've done a bunch of integrations with sign-in providers like google, yahoo, twitter, facebook, etc, some of which use openid and some of which are proprietary, and rpxnow in turn provides a "normalized" openid-like API to integrate web-app sign-in with across all those services.) In order to use their service you have to sign up with them to get assigned credentials, etc, so it might be tricky for you to test them specifically.
I will try to pull headers from the request and response of a successful request and response via httpclient, and post them here. If I have time I'll also try again with the default client with a different post target to try to figure out if this is a problem specifically with rpxnow... thanks, -Dave Fogel ------------------------------------------------------ http://restlet.tigris.org/ds/viewMessage.do?dsForumId=4447&dsMessageId=2465585
