TLS and HTTP/2 VCL features
Fastly has added several variables that expose information about the TLS and HTTP/2 attributes of a request.
When using these variables, remember the following:
- These variables are currently only allowed to appear within the VCL hooks
- Requests made with HTTP/2 will appear in custom logs as HTTP1.1 because those requests will already have been decrypted by the time Varnish sees it. Specifically, the
%rvariable will not accurately represent the type of HTTPX request being processed.
