IP address lock

Recommended Posts

So what I would love to have is the ability to lock down a Frog site by IP address.  The thought behind this is that we need to be able to prevent students from accessing a specific site unless they are in the school.  It is for testing as well as corrective education.  Can this be done in html?

This is a tricky one.  Right now, due to the many different ways it's possible to host Frog, detecting where the user is in relation is not straight-forward.  

However, I do know that the following php code:


header("Content-Type: text/plain");
print("Your IP address is: " . $_SERVER['REMOTE_ADDR'] . "\n");
print("You connected to: " . $_SERVER['HTTP_HOST'] . "\n");
print("Which internally resolves to: " . gethostbyname($_SERVER['HTTP_HOST']) . "\n");


sits on the Frog server at the top level:


It might be possible then to use the HTML widget to check this page, split the contents to get the IP address in Javascript, then hide elements based on the result.
