Sorry, I couldn’t understand the question. What does 304 have to do with Photonic?
A 304 Not Modified message is an HTTP response status code indicating that the requested resource has not been modified since the previous transmission, so there is no need to retransmit the requested resource to the client
Photonic does not seem to test if the images have already been loaded into the browser’s cache, is wanted or not such was my question
Thks
I do know what 304 is – but the question you are asking is not related to Photonic. Basically this sort of check is handled by caching plugins and your server configuration. Regular web apps simply make a request. If the response can be served from the cache as per your server’s settings it will come from there.
That being said, you shouldn’t cache Photonic’s response, particularly for Google Photos, since Google returns a new response after every 15-30 minutes. Caching it will show you broken URLs.
