#Summary Plugin for Prerender that clears PhantomJS's local storage before each request
npm install prerender-clear-local-storage

##Require the plugin
var clearLocalStoragePlugin = require('prerender-clear-local-storage');
##Use the plugin
server.use(clearLocalStoragePlugin(server));
##Configuration This plugin uses the env variable PHANTOM_LOCAL_STORAGE_PATH to determine what localstorage files to clear.
This defaults to ./LocalStorage/.localstorage* which unfortunately is useless since I cannot get PhantomJS's "--local-storage-path" to work.
You will need to set this to be the location of the PhantomJS .localstorage files on your machine. See Phantom Local Storage Locations for some suggestions.
Additionally this variable is used as a glob path so you will need to provide the wildcard of your choice. I recommend using *.localstorage so that only .localstorage files are removed.
e.g.
PHANTOM_LOCAL_STORAGE_PATH = /Users/user.name//Library/Application Support/Ofi Labs/PhantomJS/*.localstorage
You can set this variable via the commandline as shown below or if you use grunt checkout grunt-env.
PHANTOM_LOCAL_STORAGE_PATH=/path/to/phantom/localstorage/*.localstorage node server.js

#Server Code example (server.js)
var prerender = require('prerender');

});
server.use(prerender.blacklist());
server.use(prerender.removeScriptTags());
server.use(prerender.httpHeaders());
