Question: when exactly is `if-modified-since` sent? about axios-cache-interceptor

[birdspider]

update: this seems to be a firefox thing, chromium does set if-modified-since headers (or allows the cache interceptor to set them)

[birdspider]

update2: chrome https://bugs.chromium.org/p/chromium/issues/detail?id=1086809 does not show 304 in the status column but 200

As it stands, I do not think to have found a bug. Instead I found inconsistencies in FF cache handling and display issues in Chrome, I'll close this.

I don't know how to enable debug mode when using simple cdn scripts.

https://axios-cache-interceptor.js.org/guide/getting-started#install-axios-cache-interceptor

Please attach debug logs.

my bad, I didn't see that /dev is just a folder
