Since web has been taken over by youngsters charmed by "powers" of javascript and ajax, I lost interest. Since the asset in question - https://www.st.com/content/st_com_cx/en/products/microcontrollers-microprocessors.lateral-menu.html - is loaded by a javascript function, that function may also have a method to override the cache - I don't know.
Nevertheless, given .html is loaded with header parameter cache-controlmax-age=2591967 which tells my browser that that html can be cached up to 30 days. In other words, once loaded, if the loading javascript doesn't/can't enforce its reload, I will see the old content for up to 30 days. Debugger says it's a 56-kB file, transfer size is 7.6kB, cached size is around 4kB.
Sure product tree does not change that often, but when it does, changing the tree display should be something which comes with it, whatever the technical solution is. Shortening the cached time to a couple of days could be a simple option.
But this is just a minor issue. The overall clumsiness of ST web stemming from mentioned javascript abuse is much worse.
