URL REQUEST GRANTED

Looking for the current API? Open the URL_REQUEST_GRANTED reference →

Examples

This script requests a new URL after region restart:
string url;
key urlRequestId;
key selfCheckRequestId;

request_url()
{
    llReleaseURL(url);
    url = "";

    urlRequestId = llRequestURL();
}

throw_exception(string inputString)
{
    key owner = llGetOwner();
    llInstantMessage(owner, inputString);

    // yeah, bad way to handle exceptions by restarting.
    // However this is just a demo script...

    llResetScript();
}

default
{
    on_rez(integer start_param)
    {
        llResetScript();
    }

    changed(integer change)
