Subject: Réf. : Re: [saml-dev] Load balancing with SAML2

Thanks for your response : it seems to be a good solution for my problem, but it's just a draft an it's quite old (september 2006) : will it become a standard at the end ?

I've got another problem on the same subject :
Using your solution the SP will receive an unsolicited response and will be able to process it. But the relaystate information it will receive has been generated by another SP and has no sense for the actual recipient.
In my particular case the relay state allows the SP to know the precise URL asked by the user agent at the begining of the process and then allow the SP to redirect correctly the user after completing the authentication process.
So I can authenticate correctly the user but I loose the original context of it's request and don't know what to do....

Hope this helps,
