My apache server has been quite active and I like to keep an eye on various things of its operation. So I loaded tcpview to see what is happening from that perspective. I discovered that nearly everyone is using port 443 to hit my server. I looked in the apache httpd.conf and sure enough, mod_ssl is turned on. I don't need it because my site has no ads or any pay options here. Port 80 is open and one or two visitors turn up using it too.
I don't have a secure site certificate posted.
The section about mod_ssl in the apache config was just something that I looked at but didn't consider one way or the other when I set up the server, until now.
Question: Why would so many visitors be using the SSL port, or is there something else that I am missing? Is there a port 443 exploit of some sort?
