Ok, so I said that I would create some sort of offline webapp tutorial
thing. So here goes:
There is one important thing that you need for this simple, easy to
use solution. It's PHP. If you don't have it, you'll have to list all
of the files you want to cache manually.
Step 1. Create a PHP file called manifest.php
Step 2. Put the following into it:
<?php
header('Content-Type: text/cache-manifest');
echo "CACHE MANIFEST\n";
$hashes = "";
$dir = new RecursiveDirectoryIterator(".");
foreach(new RecursiveIteratorIterator($dir) as $file) {
if ($file->IsFile() &&
$file != "./manifest.php" &&
substr($file->getFilename(), 0, 1) != ".")
{
echo $file . "\n";
$hashes .= md5_file($file);
}
}
echo "# Hash: " . md5($hashes) . "\n";
?>
Step 3. Put manifest.php in the directory of the webapp that you want
to use offline
Step 4. Replace your <html> tag with <html manifest="manifest.php"> in
the index.html, index.php, etc. file
Note: That md5 hash is necessary so that every time you add a new
file, or edit one, the hash changes, forcing the device that is using
the webapp offline to re-cache, and update its offline files.

P.S. A more in-depth tutorial, that manually list files, with an
example can be found here:
