Thanks for your reply, Ok so i can metionne the website if it is not a problem:
www.luxurybagcn.com password: luxurybagcn 
I wanted to hide it as i work for a company which fight counterfeit product
and before the website desapire i wanted to download it with all pictures and
brands, i tried to capture the login (effectiveley it is not http
authentification) and filter the logout url but still make me the same
problem. I will try again..
