Strange thing : the result of MgSite.GetCurrentSession() is always empty 
in my case (MGE 2007).
Has anyone ever experienced this ?

We now share the same concern about this point.
Moreover, I 'd like to know if one always has to create a new session 
each time the application is started (by the same person on the same 
machine), or if one could re-use pre-existing session.

For instance, I'd like to do something like this, at application startup :

$userinfo=new MgUserInformation("Anonymous","");
$site=new MgSite();
$site->Open($userinfo);
if (strlen($site->GetCurrentSession())==0)
    $_SESSION['mgSessionId'] = $site->CreateSession();
else
    $_SESSION['mgSessionId'] = $site->GetCurrentSession();

... but the fact that GetCurrentSession always returns an empty string 
prevents me from trying such a thing.

Same problem. Did you get any solution in the mean time ?

I'm beginning to be fed up with this problem...
