Get input from other site

Hi allI want to get mac address in my lotus notes web application It is available using following URL I have to pass IP address

http://www.xyz.org/getmac.php?ip=172.27.27.11

I want to get this in notes web application.

I tried this by setting above url in iframe and setting field by parent.document.getElementById(‘macaddress’).value=macaddress

but it is not working because my notes application url is different i.e. http://xyz.domain.org

Please any one suggest is thee any way to get mac address from above URL on web applications field.

Thanks in advance
