I have a particular problem to use limesurvey (1.71) with an external system of URL/invitation :
I send the invitation with a custom url : un script php to serverA
this script define wich survey, wich token and wich lang must be used
and generate a header with a redirection to the classic limesurvey url : index.php?sid=xyz&token=xyz&lang=xy
the problem is that all completed responses with this system are 'NULL'
Maybe because the session are created with the same machine ?
Thanks for any suggestions.
