Session expiring for twitter oAuth - session

Question

I am using Abraham Williams' oAuth library to update a status. The application does not have a UI (other than the prompt from Twitter for credentials. Instead, the user enters a URL in the browser.
When the URL is called, I get an error: "Could not post Tweet. Error: Reason: 1".
I inserted some test code, and it seems as if the session is getting lost in between transitions: $_SESSION['tweetmsg'] is set on initial call in index.php, but then when the switch to connect.php happens, it seems as if the session is lost. Any ideas?
Following is the source code:
index.php
<?php
include_once '../../winsinclude/tw_config.php';
require_once "../../winsinclude/twitteroauth.php";
require_once "../../winsinclude/OAuth.php";
session_start();
if (empty($_SESSION['access_token'])) {
$_SESSION['tweetmsg'] = create_tweet_text();
print "<script>self.location='./connect.php');</script>";
}
$connection = new TwitterOAuth(
CONSUMER_KEY,
CONSUMER_SECRET,
$_SESSION['access_token']['oauth_token'],
$_SESSION['access_token']['oauth_token_secret']
);
if (!isset($_SESSION['tweetmsg'])) {
exit('No tweet value in session or from form');
}
$tweetmsg = $_SESSION['tweetmsg'];
$result = $connection->post('statuses/update', array('status' => $tweetmsg));
unset($_SESSION['tweetmsg']);
if (200 === $connection->http_code) {
echo 'Tweet Posted: '.$tweetmsg;
}
else {
echo 'Could not post Tweet. Error: '.$httpCode.' Reason: '.
session_destroy();
}
function create_tweet_text () {
return 'this is a test';
}
connect.php
?php
session_start();
include_once '../../winsinclude/tw_config.php';
require_once "../../winsinclude/twitteroauth.php";
require_once "../../winsinclude/OAuth.php";
$connection = new TwitterOAuth(CONSUMER_KEY, CONSUMER_SECRET);
$request_token = $connection->getRequestToken(OAUTH_CALLBACK.'callback.php');
$_SESSION['oauth_token'] = $request_token['oauth_token'];
$_SESSION['oauth_token_secret'] = $request_token['oauth_token_secret'];
$url = $connection->getAuthorizeURL($request_token);
print "<script>self.location='$url';</script>";
callback.php
<?php
session_start();
include_once '../../winsinclude/tw_config.php';
require_once "../../winsinclude/twitteroauth.php";
require_once "../../winsinclude/OAuth.php";
if (
isset($_REQUEST['oauth_token'])
&& $_SESSION['oauth_token'] !== $_REQUEST['oauth_token']
) {
echo 'Session expired';
}
else {
$connection = new TwitterOAuth(
CONSUMER_KEY,
CONSUMER_SECRET,
$_SESSION['oauth_token'],
$_SESSION['oauth_token_secret']
);
$_SESSION['access_token'] = $connection->getAccessToken($_REQUEST['oauth_verifier']);
print "<script>self.location='index.php';</script>";
}

Recently Twitter deactivated a number of http urls for oAuth and replaced them with https equivalents. If you can see the URL string http://twitter.com/oauth/request_token in the includes then it means you need to follow https://dev.twitter.com/discussions/10803 and change all the calls to https...
