Hi,
I'd like to set a captcha on my web server(s).
The code works quite fine, but I'd like to blacklist (for an amount of
time) the ips that failed
with the captcha x times.
The web server works with an SQL server, but I cannot ask the page to
check for each IP
with a request to the database.
I can't also store the blocked IP to a filename on the server, because
the site is served by several
http servers.
I thought about a DNS server for the blacklist (the same way it works
for antispam), but
perhaps someone has a better idea ?
thanks
N F
