Thanks a lot.
If you don't mind, could you tell me more (or refer) about the another
approach?
This is a good solution, but if possible, i would prefer a more waterproof
way.
Thanks
Another appoach is what Joern told you. You used a session for storing
the values, so you can check if session already has the values or not.
If session has stored values you would redirect to the next page.
There is another limit - session will not work if user has cookies
disabled. So, theoretically speaking, this is not a 100% solution. In
the same time you use session to store values and if session will not
work your form will not work as well. And if cookies are required to
use your site (it seems) then this maybe the best way to prevent
people from going back
