## 描述

The plugin adds an iframe to the footer of your website which points to `example.
com/manifest`.

That URL is an empty page that references the generated manifest file at `example.
com/manifest.appcache`.

The manifest itself is built in the following way:

 1. adds URLs of all queued scripts and styles
 2. searches theme files and folder for any images or other static assets
 3. if a theme has a 307.php template it is used as an offline fallback
 4. a timestamp of the most recently modified file is added to force appcache to refresh

The net result of all this is that your main static files are stored locally on 
your visitors devices. For mobile this greatly helps to improve download and rendering
times.

### Documentation

### Adding items to the manifest

Appcache can do more than store static assets. You could cache entire pages, or 
add fallbacks for when a user is offline.

There are 3 main sections to a manifest:

#### CACHE

The main `CACHE` section is for URLs that should be explicitly cached.

    ```
    <?php
    add_filter( 'appcache_cache', function( $urls ) {
       $urls[] = '/page-available-offline/';
       return $urls;
    } );
    ?>
    ```

#### NETWORK

This section is for specifying URLs that should _never_ be cached.

    ```
    <?php
    add_filter( 'appcache_network', function( $urls ) {
       $urls[] = '*';
       $urls[] = '/online-only-page/';
       return $urls;
    } );
    ?>
    ```

#### FALLBACK

The fallback section allows you to set fallback pages or images if the user is offline.

    ```
    <?php
    add_filter( 'appcache_fallback', function( $patterns ) {
       $patterns[] = 'wp-content/uploads/ wp-content/uploads/offline.jpg';
       return $patterns;
    } );
    ?>
    ```

#### The update header

Appcaches are refetched when the manifest file content changes so we add a few items
as comments at the top of the file.

 1. The current theme (and version if available)
 2. The most recent modified time of any files we find the server path for
 3. The size of all the files that we find a server path for
 4. get_var( “SELECT post_modified FROM $wpdb->posts WHERE post_type = ‘post’ ORDER
    BY post_modified DESC LIMIT 1” );
     return $headers; } ); ?>

### More about appcache

I strongly recommend learning more about what you can do with appcache by reading
the following articles:

 * [HTML5 Rock’s Introduction to Appcache](http://www.html5rocks.com/en/tutorials/appcache/beginner/)
 * [Application cache is a douchebag](http://alistapart.com/article/application-cache-is-a-douchebag)

## 安装

Upload the plugin to your plugins directory and activate it. There’s no configuration
involved or settings screen.
