RE : RE : How to use two distinct HttpClients on the same web site
I am sorry: it works now as expected; it was a big mistake of mine! ;o)
Thanks for your help!

Fabien,
I do not why this is happening. I would expect a well-behaved web server to redirect the request to the login page whenever the session ID cookie is not present. What web server / app server are you using?
A debug/wire log of the HTTP session might help pinpoint the problem. Please refer to the HttpClient logging guide for details on how to activate the wire/debug logging
http://jakarta.apache.org/commons/httpclient/logging.html
Please do take time to obfuscate security sensitive information in the log, such as authentication credentials, prior to posting it to the list
