Are you trying to reload the page and see the updates? Chrome used to ignore the cache on all reloads, but now it only ignores the cache for the main resource. Try doing a hard reload (e.g., ctrl+shift+r) instead and see if that helps. 

fredrick.o.jackson:  Could you please reply to comment #1?  If the issue is just normal reloads not revalidating all resources, that's expected behavior (And respecting cache headers on normal reloads results in significant bandwidth savings), and unlikely to be changed.

Not the OP, but I encountered same problem lots of times: some resources won't be reloaded even if I hard reload.

It's pretty common for files that are loaded by other file (like JS, CSS files).

Here is an example: I have a JS that will load a CSS file:

                //载入CSS
                $("head").append("<link>");
                $("head").children(":last").attr({
                    rel: "stylesheet",
                    type: "text/css",
                    href: scriptPath + '/wikiplus.css'
                });

(part of the code)

But the problem here is this CSS file will not be reloaded if I hard reload it. It still shows "from disk cache" in the Network panel in the Dev Tool.

human.peng:  By "hard reload", I assume you mean shift+reload?

Anyhow, this seems more of a Blink>Loader issue than a cache issue - the loader is what decides which resources to bypass the cache on.

Yeah I mean shift+F5 (or Ctrl+F5).

human.peng:  Thanks for the followup!  Mind filing a new bug about that?  I think we have some sort of heuristics about when the reload ends, and I suspect you're running into an issue there, which is a bit different from what this bug is about.

Post the bug number here or email it to me, and I'll attack the appropriate labels.

human.peng: ping

Sorry for being late. I was trying to make a simpler STR but failed. So here we go, the original scenario I encountered:  issue 704802 .
