 1 | # DEPRECATED
 2 | 
 3 | This repo is no longer actively being maintained.
 4 | 
 5 | ## Usage
 6 | 
 7 | Install this directory to `wp-content/mu-plugins` in your local development environment. Current WordPress.com VIP Clients will find full setup instructions in the [VIP Lobby](https://wp.me/PPtWC-2T').
 8 | 
 9 | ## Differences
10 | 
11 | This repo will help bridge the gap between WordPress.com VIP and your local development environment but will not provide a 1:1 setup. Some known missing pieces include:
12 | 
13 | * Protected Embeds
14 | * Photon is [included with Jetpack](http://jetpack.me/support/photon/) and similar to the WordPress.com CDN, but requires your development server to be publicly accessible.
15 | * The Database encoding on WordPress.com is latin1.
16 | * On WordPress.com, it is not possible to upload files from the front-end of the site.
17 | * When options are added or changed, the alloptions cache on WordPress.com is deleted.
18 | 
19 | ## Batcache
20 | 
21 | WordPress.com uses Batcache for page caching. The code is included here, but requires some setup:
22 | 
23 | 1. Install the Memcached backend
24 | 1. Copy or symlink `batcache/advanced-cache.php` to `/wp-content`
25 | 1. Turn on `WP_CACHE`, with `define('WP_CACHE', true);`
26 | 
27 | ## Concatenation
28 | 
29 | To enable nginx-http-concat, you'll need to define the `QUICKSTART_ENABLE_CONCAT` constant in `wp-config.php` and add the relevant configuration to your webserver. For example, in Nginx:
30 | 
31 | ```
32 | location /_static/ {
33 |         fastcgi_pass unix:/var/run/fastcgi.sock;
34 |         include /etc/nginx/fastcgi_params;
35 |         fastcgi_param SCRIPT_FILENAME $document_root/wp-content/mu-plugins/http-concat/ngx-http-concat.php;
36 | }
37 | ```
