I have apache server on a VPS. Sometimes the cpu loads is skyrocketing (more than 15), while there are no many visitors to the website (invision board forum).
I checked the apache status, it shows a lot of
vps.mydomain.com OPTIONS * HTTP/1.0
each on of these entries is eating part of CPU.
Apache version is latest 2.2.16. I read that it should be redirected. But I don't understand how and why should I redirect it than "prevent" it.
