Failsafename2key

This script is a example for a failsafe name2key lookup. The script will return results also when some of the given providers are unavailable.

Main Script: <lsl> list Servers = ["http://kubwa.de/_slworld/name2key.php?name=",

               "http://w-hat.com/name2key?terse=1&name=",
               "https://n2k.danardlabs.com/n2k_io.php?action=getkey&verbose=0&username=",
               "http://kdc.ethernia.net/sys/name2key.php?name="];

       }
   }

} </lsl>

Example usage: <lsl> default {

   state_entry()
   {
       llListen(1, "", "", "");
   }
   listen(integer chan, string name, key id, string msg)
   {
       llMessageLinked(LINK_THIS, llRound(llFrand(9999)), msg, "Name2Key.Lookup");
   }
   link_message(integer Sender, integer Num, string Str, key ID)
   {
       llOwnerSay((string)Sender + " => " + (string)Num + "> " + Str + ": " + (string)ID);
   }

} </lsl>
