I am developing a web app for offline use, thus I need to use the application cache functionality.
Everything works great on Chrome (15.0.874.106) but is doesn't work on Firefox (7.0.1) and Opera (11.52).
This is my cache manifest file cache.manifest.php (I have reduced it to the bare minimum):
<?php
header("Cache-Control: max-age=0, no-cache, no-store, must-revalidate");
header("Pragma: no-cache");
header("Expires: Wed, 11 Jan 1984 05:00:00 GMT");
header('Content-type: text/cache-manifest');
?>CACHE MANIFEST
CACHE:
/app/common/css/reset.css
/favicon.ico
And this is the first 4 lines of the "main" HTML document:
<!DOCTYPE html>
<html manifest="/app/mobile/cache.manifest.php">
<head>
<title>MyApp Mobile</title>
When I try and load the cache manifest (http://www.myapp.com/app/mobile/cache.manifest.php) into the browser the file is displayed correctly but when I try to load the page once offline I get the "Unable to connect" error page. Again, that just happens on Firefox and Opera.
Firebug says "0 items in offline cache" and I didn't find the way to check the application cache on DragonFly.
I am getting mad and I don't know how to debug the problem effectively on Firefox and Opera. Please help.
Thanks, Dan
For Firefox, try this little trick:
Its the "?1" that finally get Firefox to check for the latest file. That's what did the trick for me anyway. Hope this helps.
