### Rules Order
When combining `Modifier` rules with `Matcher` rules, it is important to remember that `Modifier` rules **ALWAYS** apply after the `Matcher` rules.
The following rules are both `Matchers` and `Modifiers`, so the `Matcher` portion of the rule will apply first, and the `Modifier` will apply later.
- `PathStrip`
- `PathStripRegex`
- `PathPrefixStrip`
- `PathPrefixStripRegex`
`Modifiers` will be applied in a pre-determined order regardless of their order in the `rule` configuration section.
1. `PathStrip`
2. `PathPrefixStrip`
3. `PathStripRegex`
4. `PathPrefixStripRegex`
5. `AddPrefix`
6. `ReplacePath`
