When working with the
HttpCache
in development, error messages may not become visible if apublic
response has been successfully generated for the same URL before.This is because the
HttpCache
from theHttpKernel
component by default setsstale_if_error
to 60 seconds.At least when using the
HttpCache
subclass from theFrameworkBundle
, we know about thekernel.debug
setting and its intention to support local development. In that case, we could set the defaultstale-if-error
value to 0.
