Linting changes
We introduced new compiler warnings when we detect common mistakes in use of regular expressions:
- Unanchored file extension:
req.url ~ "\.html"
most likely should bereq.url ~ "\.html$"
- Literal dots in file extensions and hostnames:
req.http.host ~ "example.com"
most likely should beexample\.com
VCL containing expressions matching these patterns will still compile and deploy as before, but warnings will be returned both in the API and management web interface.
