    ->While going through my apache logs, I found some logs indicating CONNECT

    ->I found this in 2 machines in indian ip block. My another server at US 
    ->is not affected by this. Some one else seeing this? Could this be the

    Nope, not the next wave, it's the current wave. Abusing open proxies is
    currently fashionable. It makes spammers extremely difficult to track
    without getting a hold of the logs from the abused open proxy. DNSbls
    already exist to use to try to block these. Monkeys.com and Osirusoft
    both have open proxy DNSbls.
