PHP site security + .htaccess?

Question

PHP

Redirected requests using htaccess:
RewriteRule ^viewpost/([-a-zA-Z0-9_]+)/? viewpost.php?id=$1 [L]
Now I want to deny access to the file via: ./viewpost.php?id=1
i.e. leave only: ./viewpost/1

Answer 1

RewriteRule ^viewpost\.php?id=\d+ /403.html [R=301,L]

Answer 2

A good direction was suggested by Vladlen Ultra . Make a single entry point to the index.php application and then work with REQUEST_URI. So it will be right and safe and beautiful :)
