Check MAC address

[nicolas.clo at ricoh-industrie.fr]

Hi list,



Are there any way to check validity of MAC address but one times only and not every time while
processing the virtual site ?

Actually I used this :

authorize {

	if (!Calling-Station-Id == "%{sql:SELECT mac_address FROM `mac` WHERE
mac_address='%{Calling-Station-Id}'}") {
                                update reply {
                                        Reply-Message += "MAC address %{Calling-Station-Id} was not
found in database - Login refused "
                                        }
                                        reject
                        }
}


The cache module is the only way ?
                                                                   
                                                                   
 Thanks.                                                           
                                                                   
 Nicolas.
