My case:

1. articlesubmitted.php - read the last article information from a specific username from the database.
2. addarticle.php - add article to database.

I want to do articlesubmitted.php accept visits ONLY from addarticle.php and if is possible to be readed just 1 time by the user which he submitted the article.

I found something with REQUEST\_URI but can't make to work.

How can I do that? it is possible to made from .htaccess?
