You can now configure advanced traffic management using flexible pattern matching

## Feature You can now configure advanced traffic management using _flexible pattern matching_. This feature allows you to use wildcard syntax anywhere in your path matcher configuration. You can use this feature to customize origin routing for different types of traffic and request and response behaviors. In addition, you can now use results from your pattern matching to rewrite the path that is sent to the origin. Pattern matching with wildcards is now supported for the following products: * Global external Application Load Balancer (launched previously) * Regional external Application Load Balancer * Cross-region internal Application Load Balancer * Regional internal Application Load Balancer * Traffic Director For details, see [URL maps overview: Wildcards and pattern matching operators in path templates for route rules](https://cloud.google.com/load-balancing/docs/url-map-concepts#wildcards-regx-dynamic-route). This capability is available in **General availability**.
