For your information, I'll say that :
 - there's no anonymous access allowed to my Zope site ;
 - this problem seems to be solved, even if I don't understand why : the
only think that I modified is a little python script, called by my
standard_html_header, which have to check for a few complex access
rights and then update user's session (handled by the ZSession
product)... This python script doesn't return anything, and just raise
an exception if access conditions are not OK.

Thanks anyway for any information about this point...

P.S.: one more thing : my Python script stores into ZSession a custom
persistent object (a custom "user" object used to store user's
preferences). Could this explain anything, as Toby Dickenson suggested
in his last reply ??
