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.
