Fastly VCL (Varnish Configuration Language) is a domain-specific language used to configure Fastly's edge cloud platform. It's based on the open-source Varnish Cache language but includes Fastly-specific extensions and features. With Fastly VCL, you can: - Control how requests and responses are processed - Define caching behavior - Implement content-based routing - Perform edge-based transformations - Implement security policies - And much more This documentation will help you understand how to leverage Fastly VCL to build powerful, efficient edge computing solutions.
