Function chooseTarget

Parameters

• input: {
      affinity: string;
      contentType?: string;
      hasSession?: boolean;
      method: string;
      pathname?: string;
      replicas: number;
      site: string;
      visitorPath?: string;
      writeForward?: boolean;
  }

  • affinity: string

  • OptionalcontentType?: string

  • OptionalhasSession?: boolean

    Whether the request already carries a session.

    A write with no session may establish one, and a lane cannot: its Set-Cookie is minted in the speculative run, so the client holds a session id the primary lacks (login looks like a rejected password). Pinning on this covers login, registration and reset without route names.

  • method: string

  • Optionalpathname?: string

    the front worker's own pathname, already rewritten; absent pins to the primary

  • replicas: number

  • site: string

  • OptionalvisitorPath?: string

    the visitor's own path (pathname is /serve after the rewrite)

  • OptionalwriteForward?: boolean

    whether a lane may execute a write and forward it; off pins every POST to the primary
