Except, it isn't. In theory, Litespeed follows the same syntax as Apache for the configuration files - except for the directives they don't support! And they don't document which ones they support, and which ones they don't.
So when you try something, you don't know if its not working because:
- its not supported, or,
- it is supported, but you didn't configure it correctly
Apache httpd does seem a little moribund of late, so a newcomer has to be good. But Litespeed is let down, seriously let down, by its documentation.
