Easy web challenge in the slimmest possible design.... namely none.

Solution
We are presented with a simple "under construction" text, accompanied by a GIF that doesn't exist.
<!DOCTYPE html>
<head>
<title>Under Construction</title>
</head>
<body>
<p><img src='/under_construction.gif' alt='under construction' /></p>
</body>
</html>
/flag.txt doesn't exist, but we can check robots.txt:
User-agent: *
Disallow: /flag/
The /flag/ directory contains flag.txt, but we are not allowed to see it:
<!DOCTYPE html>
<head>
<title>Restricted Access</title>
</head>
<body>
<p>You do not have permission to enter this Area. A mail has been sent to our Admins.<br/>You shall be arrested shortly.</p>
</body>
</html>
But the server simply sent us a cookie isAllowed=false, so changing that to true, we can see the flag.
