RedirectRegex

The RedirectRegex redirects a request using regex matching and replacement.

tip

Regular expressions and replacements can be tested using online tools such as Go Playground or the Regex101.
When defining a regular expression within YAML, any escaped character needs to be escaped twice: example\.com needs to be written as example\\.com.
