File (YAML)

# Redirect with domain replacement
http:
  middlewares:
    test-redirectregex:
      redirectRegex:

Configuration Options¶

`permanent`¶

Set the permanent option to true to apply a permanent redirection.

`regex`¶

The regex option is the regular expression to match and capture elements from the request URL.

Warning

Care should be taken when defining replacement expand variables: $1x is equivalent to ${1x}, not ${1}x (see Regexp.Expand), so use ${1} syntax.

Tip

Regular expressions and replacements can be tested using online tools such as Go Playground or the Regex101.

`replacement`¶

The replacement option defines how to modify the URl to have the new target URL.
