Hi Evo2,

Thank you for you tips. You are right, I will search on how to blocked back,refresh etc ... at server side by application. A friend told me to use Javascript to hide all these buttons, but it's also run at client side - also useless ...

Thanks again ....

It is impossible to block the browser with php (server side), it must be done at client side (like javascript).
Hm ... must looking for another solution ...

Thanks anyway

If the client is logged into a session, then the php code can refuse to send/resend a page. This will block "back", "reload", "forward", whatever. Sounds like someone has either been lying to you, or doesn't fully understand what they are doing.

Hi evo2,

thank you very much. So, it's possible to do it in php. I will try to implement it.
Btw, I found this, i think it is also interesting : http://samy.pl/evercookie/
To identify the client, we put "forever" cookies, which is not removed even after restarting the client browser
Combining both (client side & server side) i think will be the best solution ... i hope ...

Best Regards,
Gio
