There are information in my web site (.css, .js, .html) which are going to vary consistently however on the identical time there are a lot of others (with the identical extensions talked about above) that may at all times be static so I need to inform the browser which information it’s allowed to cache. How do I do it utilizing Go?
Alternatively, I learn that browsers at all times cache .html information, if that’s true, how the hell are dynamic web sites going to work? that will drive to make use of a whole lot of javascript and wouldn’t permit the usage of methods comparable to templates. It’s price mentioning that I learn such info in previous posts and I couldn’t discover present info, however my intuition tells me that at the moment any browser caches .html information, am I proper?
Static pages are rendered as they’re by Go.
Static pages with dynamic knowledge the place the information is handed to the template to {{.}} and rendered by Go.
Totally dynamic pages is often constructed by Javascript and rendered by the browser.
And there are pages rendered in Go and elements of the content material is up to date utilizing Javascript and innerHTML.
That’s how I interpret it. However the time period “dynamic” is floating.

Will the identical guidelines I put within the header for the .html apply to them or is that impartial for every file?
Don’t do something on the consumer facet. The server signifies the caching management. The browser is aware of what to do from the cache management header for each useful resource it retrieves.
Right here’s what you are able to do on the consumer, however I’d keep away from it and simply set the suitable header on the server.
