Sure, but his phpinfo() does show REDIRECT_* vars as it is the server doing the redirect. An external redirect (HTTP Location header) is not going to show anything as it has nothing to do with the server.-Rasmus On Tue, 24 Dec 2002, John Nichel wrote:He's looking to see if there is a redirect. The thing I'm seeing is that if the redirect comes from a php header call, or a url rewrite from the server, nothing is set for REDIRECT_URL or HTTP_REFERER. This is the $_SERVER output I get on my machine from a url rewrite and php header Array ( [DOCUMENT_ROOT] => /webserver/docs/vhosts/backup [HTTP_ACCEPT] => text/xml,application/xml,application/xhtml+xml,text/html;q=0.9,text/plain;q=0.8,video/x-mng,image/png,image/jpeg,image/gif;q=0.2,text/css,*/*;q=0.1 [HTTP_ACCEPT_CHARSET] => ISO-8859-1, utf-8;q=0.66, *;q=0.66 [HTTP_ACCEPT_ENCODING] => gzip, deflate, compress;q=0.9 [HTTP_ACCEPT_LANGUAGE] => en-us, en;q=0.50 [HTTP_CACHE_CONTROL] => max-age=0 [HTTP_CONNECTION] => keep-alive [HTTP_COOKIE] => PHPSESSID=a4a0a7c613f817b0344ff70af03b88ae [HTTP_HOST] => www.backup.jcn [HTTP_KEEP_ALIVE] => 300 [HTTP_USER_AGENT] => Mozilla/5.0 (X11; U; Linux i586; en-US; rv:1.0.1) Gecko/20020823 Netscape/7.0 [PATH] => /sbin:/usr/sbin:/bin:/usr/bin:/usr/X11R6/bin [REMOTE_ADDR] => 11.11.68.1 [REMOTE_PORT] => 2380 [SCRIPT_FILENAME] => /webserver/docs/vhosts/backup/referer2.php [SERVER_ADDR] => 11.11.68.3 [SERVER_ADMIN] => [EMAIL PROTECTED] [SERVER_NAME] => www.backup.jcn [SERVER_PORT] => 80 [SERVER_SIGNATURE] => Apache/1.3.26 Server at www.backup.jcn Port 80 [SERVER_SOFTWARE] => Apache/1.3.26 (Unix) PHP/4.2.3 mod_perl/1.27 [GATEWAY_INTERFACE] => CGI/1.1 [SERVER_PROTOCOL] => HTTP/1.1 [REQUEST_METHOD] => GET [QUERY_STRING] => [REQUEST_URI] => /referer2.php [SCRIPT_NAME] => /referer2.php [PATH_TRANSLATED] => /webserver/docs/vhosts/backup/referer2.php [PHP_SELF] => /referer2.php [argv] => Array ( ) [argc] => 0 ) But if I use JavaScript or Meta refresh to do the redirect, I get the HTTP_REFERER. I also get it when I link to the page from another. I didn't get any REDIRECT variables in any of the cases. Are these supposed to be in the $_SERVER array? Rasmus Lerdorf wrote:Isn't the question about REMOTE_HOST? Why are you talking about referer stuff at all? The two have nothing to do with each other. REMOTE_HOST is the resolved version of REMOTE_ADDR and is rarely set as it is way too time consuming to do a reverse DNS lookup on each ip that connects to your web server. But, REMOTE_ADDR is always set and you can use that to see where requests are coming from. But this has nothing to do with the referer. If you are looking to detect the redirect, then the presence of REDIRECT_* variables will tell you that, but again, this has nothing to do with the referer. If you want to know where something was redirect from, try REDIRECT_URL. -Rasmus On Tue, 24 Dec 2002, John Taylor-Johnston wrote:John, CC: a copy of your next posts. I'll be back on Friday. Jingle Bells and all. Thanks for thinking about it. What about turning on: session.referer_check = Or soemthing else in php.ini John John Nichel wrote:Well, that won't help then. I saw that REMOTE_PORT was different in your last two emails, but if it's ever changing.... I'm doing a little testing here on my end and have discovered that REFERER isn't set if the server is doing a redirect. I made a simple little two page script. The first page just contained this (the site doesn't have DNS outside of my network)... header ( "Location: http://www.backup.jcn/referer2.php"; ); and referer2.php contained... print_r ( $_SERVER ); When I went through the redirect, REFERER was NOT set, but when I clicked on a link from another page, it was set. I'll look at it a bit longer to see if there is anything out there to tell it was redirected, but it's not looking good. John Taylor-Johnston wrote:[SERVER_PORT] => 80Server port does not change. Will it do anything to change my php.ini? session.referer_check = It is set to nothing at the moment, copied and pasted. How do I check for the port number? My redirects come through:[REMOTE_PORT] => 1070 [REMOTE_PORT] => 1074They are also increasing. It's a bit like a counter :) no? Even the link to http://compcanlit.usherbrooke.ca makes remote_port increase:[REMOTE_PORT] => 1079John John Nichel wrote:Like John said, REFERER isn't always set, and that looks to be the case here. One thing I did notice is that the redirect comes thru on a different port. If this is consistant, you may be able to use this.
