HTTP status codes cached by default

Last updated 2020-06-01

Fastly caches the following response status codes by default. In addition to these statuses, you can force an object to cache under other states using conditions and responses.

Code	Message
`200`	OK
`203`	Non-Authoritative Information
`300`	Multiple Choices
`301`	Moved Permanently
`302`	Moved Temporarily
`404`	Not Found
`410`	Gone

TIP

You can override caching defaults based on a backend response. For example, if you don't want 404 error responses to be cached for the full caching period of a day, you could add a cache object and then create conditions for it.

To cache status codes other than the ones listed above, set beresp.cacheable = true; in vcl_fetch. This tells Varnish to obey backend HTTP caching headers and any other custom ttl logic. A common pattern is to allow all 2XX responses to be cacheable:

sub vcl_fetch {
  # ...
  if (beresp.status >= 200 && beresp.status < 300) {
    set beresp.cacheable = true;
  }
  # ...
}
