Twitter for Locify

There have been some changes in format for older versions of Locify. See documentation for Locify 0.8.1 and older.
If you plan support for versions older than 0.8.5, you need to detect client version and serve correct screen.

This sample service allows user to save his updates on Twitter with GPS position. It also supports viewing public, user and friend timelines, favorite updates and account information using internal browser. It supports authentication to Twitter and uses settings for saving item count and default adding gps coordinates to statuses.

Answer after update status

In case user is not logged a 401 HTTP status is returned and user login screen shows up. In case everything is OK, this alert shows up (alert is also used for some error messages): 
<?xml version="1.0" encoding="utf-8" ?><!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
<html xmlns="http://www.w3.org/1999/xhtml" xmlns:locify="http://client.locify.com/locify_ns/1.0" xml:lang="en" lang="en">
<head>
	<title>Info</title>
</head>
<body class="alert">
	<div>
		<p class="text">Your Twitter status has been updated.</p>
		<a href="http://services.locify.com/twitter/start" class="next">next</a>
		<locify:timeout value="3000" />
	</div>
</body>

</ul>

Other

After selecting one of the Timelines, Favorites or Account, internal browser is called. Regular XHTML with links, images etc. is used. After selecting Sign in, server checks if user is logged in and if not, HTTP status 401 is sent back.
