Regex rewrite rule not working in .htaccess

I have an .htaccess file that's using several rewrite rules. They don't seem to be working on a server I'm testing on, but they work on another server. I tested using a rule that doesn't use a regex, and that seems to work. Is there any way that regex rules can be disabled (or enabled) in Apache?

+4  A: 

No, regular expressions are fundamental for mod_rewrite. But it might be possible that your servers have different versions and don’t use the same regular expression engine (POSIX ERE since 1.2, PCRE since 2.0).

What's a quick and easy way to determine which engine the server is using?

@Calvin L: My post is a little ambiguous. mod_rewrite supports only one regular expression engine. The version of Apache tells you what engine is used.

Thanks Gumbo, turns out the live server is on Apache 1.3.41, and my local server is on 2.2.11. Oy! Thank you so much, that really helped.
