I made a client-side HTML page (a basic SPA) which displays some information, via an IFRAME card.
When changing the HTML/CSS/JS code, the page is not updated in the card. I guess that it is cached somewhere (to the point that adding ?whatever=1 does not force a reload).
Ha, I did clear the browser cache (sorry for not mentioning it) but cleared once again “to make sure”.
Half of the pages were updated, and then another cleanup refreshed all of them. This is strange but it works so fine for me
