it's still there but it requires a login, anyway, I copied it here

well, I'm successfully using it over http 1.1 (I suppose that's the only 
protocol currently supported by fpWeb)

It'd be enough for it to continue working as it is....

...when I have to modify the project using the above hack, though this 
could happen next month, next year or never. In that case I could try to 
adapt the code to the new paradigm but, as I said, I'd prefer it to 
continue working as it is ;-)
(most probably because the http server part won't be the part I'll need 
to modify).
