Logout Endpoint Response URL with parameters

Hi all,

I have configured a RP (Service Provider) in ADFS 2.0 with a SAML Logout Endpoint:

Binding: POST

URL: http://MypartnerFQDN/logout

All work fine, after logout ADFS redirect user on page: http://MypartnerFQDN/logout

Now my Partner send me a logout url with parameters that are variable:

ex: https://MYADFSfqdn/adfs/ls/?wa=wsignout1.0&spid=STRING&spurl=OTHERURL

and tell me that the URL that I use in the endpoint for response after logout will be WITH same parameters.

ex: http://MypartnerFQDN/logout?spid=STRING&spurl=OTHERURL

It's possible with ADFS 2.0 to customize response url?

Many thanks.

Raffaele
