Apache to LiteSpeed: Anything I need Worry About?

Alright,

I’m thinking of putting LiteSpeed on my server next week and running that instead of Apache.

The question is, should I be worried about anything? My site is custom-coded PHP and I do use a lot of mod_rewrites and redirects through htaccess files.

Could that become an issue?

What should I look out for before stopping apache and starting litespeed?

Thanks
Ryan
