So I would imagine you have something else in the mix that's at fault here that's doing a manual redirect to /Login and dropping it. Realize that a standard request intercept in the SP never redirects to /Login. if that happens, you're doing it (in the broadest sense of "you"), not the SP.
Yes , I don't force requireSession (it is set to 0) , I want my users to 
browse the site freely without beeing connected:

<LocationMatch /cgi-bin/koha/.*>
  AuthType shibboleth
  ShibRequestSetting *requireSession 0*
   require shibboleth
</LocationMatch>

I want them to connect only when necessary (placing a hold on a book in 
this case) , so I use "lazy session" as I understand it .
when they click on .../cgi-bin/koha/opac-reserve.pl?biblionumber=74745 
it matchs the above LocationMatch /cgi-bin/koha/.* and the "require 
shibboleth" through shibd starts <SessionInitiator type="Chaining" 
Location="/Login" id="Login" >
  as I understand the flow .
Now I am presented with the intermediary page :

<p>If you have a shibboleth account,
please<a  href="https://site.domain.fr/Shibboleth.sso/Login?target=https://server.domain.fr/cgi-bin/koha/opac-reserve.pl  <view-source:https://mediatheques.mines-telecom.fr/Shibboleth.sso/Login?target=https://mediatheques.mines-telecom.fr/cgi-bin/koha/opac-reserve.pl>">click here to login</a>.</p>

<h4>Local Login</h4>
<p>If you do not have a shibboleth account, but a local account, you can still log in :</p>


where the hardcoded link indeed removed the *?biblionumber=74745* .
It did took the referer 
target=https://server.domain.fr/cgi-bin/koha/opac-reserve.pl 
<view-source:https://mediatheques.mines-telecom.fr/Shibboleth.sso/Login?target=https://mediatheques.mines-telecom.fr/cgi-bin/koha/opac-reserve.pl> 
but not the following query string,
is there a way to preserve it ? is it available in a http environnement 
variable ? elsewhere ?

thanks for you help .
