accept POST from only own server

Question

i have developed a project in PHP now i need to process those POST DATA which have been sent from my own server !
how to do it ?
REFERRER is not a solution, as it can be blocked/removed or changed easily !
is there code to stop it in .htaccess ?

Answer 1

You could try to use cryptographic nonce : Typical client-server communication during a nonce-based authentication process including both a server nonce and a client nonce ( this client nonce could be built using the nonce recived from the server ) .

Now this doesn't make you super secure ( as there will be people who would be able to bypass this rather easy ) it will be harder for most floks to make a post to you're website .

( this image shows you how to use nonces in an authetification process , however you could use it for non authentification purposes )
