How do you know the server have litespeed?

[joe168]

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

We use APACHE litespeed. Using the normal litespeed version causes litespeed service to fail every hour..

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