It is not clear to me what you are saying. You don't want an index.html, 
but "curl -l" does exactly that, only less formatted - but you don't 
parse it, you just want to compare it with a previous version. Or not?

Anyway, HTTP is not FTP, and not you, not me, not gambas can do 
something about that.

Please note that asking an ftp server to generate a listing is not a 
guarantee - every server can do whatever it want with its listing, just 
like an http server. The listing can come out sorted, not sorted, with 
or without added comments (550 - xxxx) and so on. The listing often 
seems "normal" because unix tends to simply launch a /bin/ls, but this 
can not be held always for true.
At least HTTP *has* a way to know if something has been changed since a 
date, while ftp does not.

So there are still only two possibilities - 1) ask for modifications, or 
2) determine them by yourself.
