Sends data from your Sencha Touch or Ext JS proxy to your server using traditional POST variables (instead of JSON or XML).

UrlEncodeWriter.js

/*
Send data to the server as POST parameters.  Refer to the documentation for {@link Ext.data.writer.Json}
for more details on proxy writers.  Use "urlencode" as the writer type.  For example, your store might
look something like this:

Ext.define('App.store.ExampleStore', {
	extend: 'Ext.data.Store',

	requires: [
		'App.model.ExampleModel'
	],

	config: {
		autoLoad: true,
		model: 'App.model.ExampleModel',
		storeId: 'StudentScores',
		proxy: {
			type: 'rest',
			url: 'example.php',
			reader: {
				type: 'json'
			},
			writer: {
				type: 'urlencode'
			}
		}
	}
});
