Example

A common use case is to convert an old URL format like example.com/contentID=12345 to a more concise format such as example.com/content/12345.

The following configuration converts the request URI path to lowercase, which normalises URLs for better caching and consistency.

http.request.uri.set:
  path: ${lower(http.request.uri.path)}
  query: ${http.request.uri.query}
