Wow
There are very few information about it on the internet.

So the equivalent would be

RewriteCond %{REQUEST_URI} =%{ORG_REQ_URI}

(I guess)

Now I can solve my problem.
However, still the fact that it incompatibility with apache rewrite module.

Thus Litespeed is not completely Apache interchangeable since users have to tweak something when working with Litespeed.

Anyway, thank you for now.
