Today the minimum version of VCL available across our network increased, unlocking the following changes:

Variable re-categorization

We have re-categorized a lot of VCL variables in this release to reduce the number classified as miscellaneous. The reference pages for these variables have moved to new URLs. The old ones will redirect.

Improved content

  • beresp.cacheable now includes a reference for which HTTP status codes are considered cacheable by default
  • req.backend now describes how it gets serialized

New variables
