问题
I got an HTML5 page that works with CHROME and SAFARI but using Internet Explorer 11 it does not work, my cache manifest is valid according to http://manifest-validator.com/ and I'm very frustrated...
here's the paste of the AppCache manifest:
#version 1.1 12-20-2013
CACHE:

and the devel site is this one:
The error on IE11 is the following: Something like: The resource doesn't exist on server.
回答1:
Add
header("Cache-Control: no-cache, must-revalidate");
To any data php returns. The default Cache-Control header from php contains "no-store" which will mess up the appCache in both IE 11 and Firefox.
回答2:
IE 11 does not work with appcache if some file in the manifest (or the index itself) works with PHP SESSION
You need to remove from every PHP any of this atributtes:
session_start
cache no expire no store
make sure MimeType is correct
回答3:
Add
header("Cache-Control: no-cache, must-revalidate");
after session_start()
