This example dynamic redirect for zone example.com will redirect visitors from an old URL format that included the locale (for example, /en-us/<page_name>) to the new format /<page_name>.
Example
When incoming requests match
^/[A-Za-z]{2}-[A-Za-z]{2}/If you are using the Expression Editor, enter the following expression:
http.request.uri.path matches "^/[A-Za-z]{2}-[A-Za-z]{2}/"
Then
regex_replace(http.request.uri.path, "^/[A-Za-z]{2}-[A-Za-z]{2}/(.*)", "/${1}")The function regex_replace() allows you to extract parts of the URL using regular expressions’ capture groups. Create capture groups by putting part of the regular expression in parentheses. Then, reference a capture group using ${<num>} in the replacement string, where <num> is the number of the capture group.
For example, the redirect rule would perform the following redirects:
| Request URL | Target URL | Status code |
|---|---|---|
example.com/en-us/meet-our-team | example.com/meet-our-team | 301 |
example.com/pt-BR/meet-our-team | example.com/meet-our-team | 301 |
example.com/en-us/calendar?view=month | example.com/calendar?view=month | 301 |
example.com/meet-our-team | (unchanged) | n/a |
example.com/robots.txt | (unchanged) | n/a |
