Summary

CEL interpolation support has been extended to the URL field in the forward-internal action, allowing dynamic routing based on request attributes like URL, host, and headers. This capability enables the redirection of requests to different internal endpoints by extracting elements such as subdomains from the request host variable, thereby simplifying complex workflows like site-to-site connectivity without the need for VPNs. Practical applications include dynamically routing traffic to customer networks or developer machines using unique subdomains and custom headers, streamlining the management of numerous endpoints. Organizations can use CEL interpolation to connect SaaS applications directly to customer networks or direct requests to individual developer environments, enhancing flexibility and efficiency in traffic management. The documentation provides further insights into CEL interpolation, encouraging users to explore its potential and share their use cases through community channels.
