How do you know the server have litespeed?
 

I have check on a server that have litespeed php info and it have litespeed word in it. The host that I with say their server have litespeed and I cannot find any word such as litespeed in php info. I tell them that they don't have litespeed in their server and they say we only install

Is there such as apache litespeed? How do we know the server have it? Can someone help. Thanks.

use domaintools to check the ip/domain, it should give you the name of the webserver in the whois info.

www.who.is
enter their domain name there and you can see the webserver type on next page

another simple way :-
know a domain on that server and enter url:-
http://www.domain.com/litespeed/
you will see error page either apache error / litespeed :D

It won't works if they give custom 404 error :) If you're using *nix, just simple enter this string :
