问题
I have a problem with .css files not being updated while I change it, and everything points to caching. I have cleared browser cache, added versioning, or even changed the link to another .css file, but nothing helped.
There are two subquestion:
a) what else can I do about caching issues?
b) when can I be sure that every possible solution was tested and not working, so it's highly unlikely that the problem is in caching?
Both .php and .css files are on localhost, in XAMPP sandbox - when the previous options failed, I suspect the problem might be either in Apache or in any other part of XAMPP, or that Firefox treats it somewhat special for not being in the "real internet", and thus didn't remove cache for it despite advertising "no cache".
EDIT: I use Firefox 21.0. I tried the same under Google Chrome 27.0.1453.116 m, with no effect too.
EDIT2: the original question was resolved, and it proved NOT to be about caching. Just in case it would help anyone in the future, I add a brief list of related questions and accept the answer that adds something new to their answers:
Stylesheet not updating
Firefox browser does not reload the update CSS/JS files
What is an elegant way to force browsers to reload cached CSS/JS files?
