Sorry to bother you once again Joe,
but knowing that you're one of the Proxo experts here,
perhaps you could make it faster or more accurate or more ..... ,
did I construction the URL = "..." the way it should, or could you make some corrections ?

Would someone be interested if I made one for this forum, as for me it's more some time wasting lol, but perhaps some people would also use it because of faster loading times, and destressing the server ?

Thanks for the help.
