The situation is I have to protect him now projects that reflect the sea is calling to fix security flaws in web
Eg when running web path
http://localhost:60864/DO_AN/Form_BA...px?MaBaiHat=11 (will appear 11 songs)
and he asks that if anyone entered
web will surely fail immediately and ask them to remedy this error.
And also asked to make up their web network.
1 thing is that when people type in http://localhost:60864/DO_AN/ will see his form and took the code and data (images, for example) how to minimize this.
So I ask you any experience with their teacher at the only school I have not learned about these things but do not have time anymore
