如何调试IE11 APPCACHE

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.

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

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.

Add

header("Cache-Control: no-cache, must-revalidate");

after session_start()
