When not to use mod_rewrite

This document supplements the mod_rewrite reference documentation. It describes perhaps one of the most important concepts about mod_rewrite - namely, when to avoid using it.

mod_rewrite should be considered a last resort, when other alternatives are found wanting. Using it when there are simpler alternatives leads to configurations which are confusing, fragile, and hard to maintain. Understanding what other alternatives are available is a very important step towards mod_rewrite mastery.

Note that many of these examples won't work unchanged in your particular server configuration, so it's important that you understand them, rather than merely cutting and pasting the examples into your configuration.
