On my dietpi I installed the LAMP stack. During development of websites I sometimes have minor changes and sometimes larger.
When I change only a couple of bytes my Apache will not deliver the new version of a page but still the one without the small change. After a while (some seconds) it will deliver the new version.
If I do larger changes Apache will immediately deliver the latest version.
Any idea what I can change in my Apache configuration to always deliver the latest version of a file without taking care of the amount of changes?
