Remove locale from URL path

This example single 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>.

When incoming requests match

• Field: URI Path
• Operator: matches regex
• Value: ^/[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

• Type: Dynamic
• Expression: regex_replace(http.request.uri.path, "^/[A-Za-z]{2}-[A-Za-z]{2}/(.*)", "/${1}")
• Status code: 301
• Preserve query string: Enabled

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
