Web Form to send messages in-world from a webpage

The following LSL script requests a new LSL Server public URL, then makes an HTTP call that updates a DB with the public URL of the script. A form read the URL from the DB and lets users send a message from a web page to the script.
It supports an automatic system to work around the dynamic URL problem. This requires a web hosting with PHP/MySQL support and a field in a database.
It sort-of works (only in a few sims on the beta grid!), but it's not complete yet; also, it's probably horrible code, I'm not a developer - don't use this if you don't know what you're doing.

       state_entry()
       {
           llRequestURL();     
       }

       http_request(key id, string method, string body)
       {
           if (method == URL_REQUEST_GRANTED)
           {
               my_url = body;
               llOwnerSay("chiamero' questo indirizzo: " + base_url + my_url);
               llSetObjectDesc(my_url);
               http_request_id = llHTTPRequest(base_url + my_url, [HTTP_METHOD, "POST"], "");
