Wildcard matching and referencing

You can use the asterisk (*) in any URL segment to match certain patterns. For example, example.com/t*st would match:

• example.com/test
• example.com/toast
• example.com/trust

example.com/foo/* does not match example.com/foo but example.com/foo* does match.

​​ Helpful tips

• To match both http and https, write example.com. Writing *example.com is unnecessary.
• To match every page on a domain, write example.com/*. Writing example.com will not work.
• To match every page on a domain and its subdomains, write *example.com/*. Writing example.com won’t work.
• A wildcard (*) in a Page Rule URL will match even if no characters are present and may include any part of the URL, including the query string.

​​ Referencing wildcard matches

You can reference a matched wildcard later using the $X syntax, where X indicates the index of a glob pattern. As a result, $1 represents the first wildcard match, $2 represents the second wildcard match, and so on.

The $X syntax is especially useful with the Forwarding URL setting. For example, you could forward http://*.example.com/* to http://example.com/images/$1/$2.jpg.

This rule would match http://cloud.example.com/flare.jpg which ends up being forwarded to http://example.com/images/cloud/flare.jpg.

To add a $ character in the forwarding URL, escape it by adding a backslash \ in front like \$.
