by relative you mean a target like this ? (using a relative path)

&target=../../opac-detail.pl?biblionumber=84779

but my need is is to get back to the previously selected book number, it 
can be any "bibblionumber" here ... so I cannot hardcode it as above.

If there is no application session cookie already set (anonymous 
browsing) , the application sends the user to a intermediary login page, 
the login button ( NativeSPSessionInitiator) containing :

https://catalogue.mines-telecom.fr/Shibboleth.sso/Login?providerId=https://idp.tem-tsp.eu/idp/shibboleth&target=https://catalogue.mines-telecom.fr/cgi-bin/koha/opac-user.pl

here, I want the target to be set to the previous page , in that 
specific case

&target=../../opac-detail.pl?biblionumber=84779

but that "previous page" depend on the users browsing, next time it 
could be opac-detail.pl?biblionumber=999999

can the target be something like &target=$referer !?

Thanks .
