Subject Re: [users@httpd] Strange, Disconcerting Access Log Entries
Date Sun, 03 Nov 2002 17:59:54 GMT
>From the HTTP-rfc:

CONNECT

   This specification reserves the method name CONNECT for use with a
   proxy that can dynamically switch to being a tunnel (e.g. SSL
   tunneling [44]).

My guess is, that somebody is abusing your Apache server to forward/tunnel
connections to a SMTP-server. This is probably to send SPAM.
If you have been hacked or not is a good question. But since you son't seem
to really know what CONNECT is/means, it could also be that your server is
not properly configured.

Keep us informed! Never seen such a case/report, but also never figured that
a spammer could abuse Apache like this.

Kind Regards,
Sander Holthaus
