!!! note
Please note that `regex` and `replacement` do not have to be set in the `redirect` structure if an entrypoint is defined for the redirection (they will not be used in this case).
Please note that `regex` and `replacement` do not have to be set in the `redirect` structure if an `entrypoint` is defined for the redirection (they will not be used in this case).
Care should be taken when defining replacement expand variables: `$1x` is equivalent to `${1x}`, not `${1}x` (see [Regexp.Expand](https://golang.org/pkg/regexp/#Regexp.Expand)), so use `${1}` syntax.
Regular expressions and replacements can be tested using online tools such as [Go Playground](https://play.golang.org/p/mWU9p-wk2ru) or the [Regex101](https://regex101.com/r/58sIgx/2).
