On my localhost, I can see HTTP_REFERER information, but I cannot see it on the server. The variable does not show when looping through the $_SERVER collection, although all the other server variables, such as HTTP_USER_AGENT, HTTP_ACCEPT, etc., are showing as expected.

You can see this at [http://mywonderyears.org]. If you click on Userlog, you will see the server variables printed. If you go to the Home page, then back to Userlog, the referer information SHOULD BE index.php, however, the referer information is not there.

Is it being blocked, and if so, why, and can it be unblocked?

I posted a similar question last week. Instead of:

$HTTP_SERVER_VARS['HTTP_REFERER'];

Use:

$_SERVER['HTTP_REFERER'];

Use:

$_SERVER['HTTP_REFERER'];

That is what I am using. Here's my code:

$ip = $_SERVER['REMOTE_ADDR'];
$method = $_SERVER['REQUEST_METHOD'];
$uri_stem = $_SERVER['SCRIPT_NAME'];
$uri_query = $_SERVER['QUERY_STRING'];
$status = "200";
$user_agent = $_SERVER['HTTP_USER_AGENT'];
$cookie = $_SERVER['HTTP_COOKIE'];
if(isset($_SERVER['HTTP_REFERER']))
{$referer = $_SERVER['HTTP_REFERER'];}
else
{$referer = "";}
$host = $_SERVER['HTTP_HOST'];
$accept = $_SERVER['HTTP_ACCEPT'];


$insert = "INSERT INTO stats".
"(ip, method, uri_stem, uri_query, status, user_agent, cookie, referer, host, accept, added)".
" VALUES ('".$ip."', ".
"'".$method."', ".
"'".$uri_stem."', ".
"'".$uri_query."', ".
"200, ".
"'".$user_agent."', ".
"'".$cookie."', ".
"'".$referer."', ".
"'".$host."', ".
"'".$accept."', ".
"NOW())";

echo $insert;
echo "<br>".$referer;

On my development server (localhost), this is what is echoed out to the client:
insert: INSERT INTO stats(ip, method, uri_stem, uri_query, status, user_agent, cookie, referer, host, accept, added) VALUES ('127.0.0.1', 'GET', '/wonderyears/servervar.php', '', 200, 'Mozilla/4.0 (compatible; MSIE 7.0; Windows NT 5.1; .NET CLR 2.0.50727; .NET CLR 3.0.04506.648; .NET CLR 3.5.21022)', '', 'http://localhost/wonderyears/calendar.php', 'localhost', '*/*', NOW())
referrer:http://localhost/wonderyears/calendar.php

On the production server, this is what is echoed out back to the client:
insert: INSERT INTO stats(ip, method, uri_stem, uri_query, status, user_agent, cookie, referer, host, accept, added) VALUES ('66.214.143.224', 'GET', '/servervar.php', '', 200, 'Mozilla/4.0 (compatible; MSIE 7.0; Windows NT 5.1; .NET CLR 2.0.50727; .NET CLR 3.0.04506.648; .NET CLR 3.5.21022)', '', '', 'mywonderyears.org', 'image/gif, image/x-xbitmap, image/jpeg, image/pjpeg, application/x-shockwave-flash, application/vnd.ms-excel, application/vnd.ms-powerpoint, application/msword, application/x-ms-application, application/x-ms-xbap, application/vnd.ms-xpsdocument, application/xaml+xml, */*', NOW())
referrer:

Notice that referrer has a value on the development server, and is blank on the production server.

Then I would try:

$HTTP_SERVER_VARS['HTTP_REFERER'];
