  title: Fastly Upload Custom VCL
  summary: Clone the active version, upload a main custom VCL file, then activate the new version.
  description: >-
    For full control over edge logic, Fastly lets you upload a complete custom
    VCL file rather than relying on generated VCL. This workflow clones the live
    version into a draft, uploads a custom VCL file marked as the main entry
    point on the clone, and activates the new version. Every step spells out its
    request inline so the flow can be read and executed without opening the
    underlying OpenAPI description.
