KBcaution.png Important: Never ever forget to release a URL again which you have requested! URLs are region resources just like prims. If you take them all you can get into big trouble with the sim owner and/or estate managers.

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)
    {
        if (change & (CHANGED_OWNER | CHANGED_INVENTORY))
        {
            llReleaseURL(url);
            url = "";

            llResetScript();
        }

        if (change & (CHANGED_REGION | CHANGED_REGION_START | CHANGED_TELEPORT))
            request_url();
    }

    state_entry()
    {
        request_url();
    }

    http_request(key id, string method, string body)
    {
        integer responseStatus = 400;
        string responseBody = "Unsupported method";

        if (method == URL_REQUEST_DENIED)
            throw_exception("The following error occurred while attempting to get a free URL for this device:\n \n" + body);

        else if (method == URL_REQUEST_GRANTED)
        {
            url = body;
            key owner = llGetOwner();
            llLoadURL(owner, "Click to visit my URL!", url);

            // check every 5 mins for dropped URL
            llSetTimerEvent(300.0);
        }
        else if (method == "GET")
        {
            responseStatus = 200;
            responseBody = "Hello world!";
        }
        // else if (method == "POST") ...;
        // else if (method == "PUT") ...;
        // else if (method == "DELETE") { responseStatus = 403; responseBody = "forbidden"; }

        llHTTPResponse(id, responseStatus, responseBody);
    }

    http_response(key id, integer status, list metaData, string body)
    {
        if (id == selfCheckRequestId)
        {
            // If you're not usually doing this,
            // now is a good time to get used to doing it!
            selfCheckRequestId = NULL_KEY;

            if (status != 200)
                request_url();
        }

        else if (id == NULL_KEY)
            throw_exception("Too many HTTP requests too fast!");
    }

    timer()
    {
        selfCheckRequestId = llHTTPRequest(url,
                                [HTTP_METHOD, "GET",
                                    HTTP_VERBOSE_THROTTLE, FALSE,
                                    HTTP_BODY_MAXLENGTH, 16384],
                                "");
