preemptive authentication

Dear all,

I am facing the problem that the HTTP protocol client doesnt seem to support "preemptive authentication". It always waits until it receives a 401 reply and then makes the authentication and resends the request. This is causing traffic and is slowing down the request processing.

Any solution for this?

Thanks, Best regards,
Martin

Depending on the authentication mechanism, that may not be possible because the 401 response often carries an Authorization header that provides contextual information necessary to start the authentication interaction.

What authentication mechanism do you want to use?

To be honest - I dont know exactly.

Our business partner wrote me a mail that we should use preemptive authentication to minimize traffic.
