Hi all, Morning.
I'm finally sure that the problem is the thrid-party cookies that are automatically blocked in medium security level in IE6, to solve taht i must write a custom p3p policy.
Hope that will work.
Also, i suggest (if anyone will have similar problems in the future), read the book on p3p policies (it is great) :
"Web Privacy with P3P by Lorrie Faith Cranor "out since2002.
Wish me luck!
Good day everyone!
Sofia
