no coockie and proxy user redirect

[haraldl]

hi coding talk!

i´m seraching for the best solution to redirect browsers wich :
-accept no coockies
- use proxy

any elegant solution ?

[something else]

I like rapidshares Proxy redirection setup that redirects web proxys to there site without the proxy...
im guessing it is done on finding out what the url is but im unsure how you go about redirecting it to same page without the web proxy being used


for your answer:

//code removed as incorrect .... use gums code below :P 

at a guess on web proxys:

if($_SERVER['REQUEST_URI']!="your file path")
{
 header("Location: http://yoursite.con");
exit;
}

for proxy, the example by something else if also good for some web proxies

if ($_SERVER['HTTP_X_FORWARDED_FOR'] || $_SERVER['HTTP_X_FORWARDED'] || $_SERVER['HTTP_FORWARDED_FOR'] || $_SERVER['HTTP_VIA'])
{
    header('Location: http://yoursite.com');
} 

and for cookie
first of all set cookie for example on index page add after <?php:

setcookie("your_cookie_name", 1, time()+3600);  /* expire in 1 hour */ 

on subpages add this:

if (!isset($_COOKIE['your_cookie_name']))
{
    header('Location: http://yoursite.com/index.php'); /* if no cookie set, redirect back to index (all browsers which dont support cookies will be redirected to the index page all the time */
}

Just was thinking is something like that would be better that something like this but i didn't know what globals they send. Thanks.

$host_ip = gethostbyaddr($ip);
if (strcmp($ip, $host_ip) == 0) {
echo 'Proxy';
}

I like gums solution.many proxy servers use x_forwarded_for .
to try to give a coockie and request this , is a nice solution.
thank you gum.i will setup this.

for proxy, the example by something else if also good for some web proxies

if ($_SERVER['HTTP_X_FORWARDED_FOR'] || $_SERVER['HTTP_X_FORWARDED'] || $_SERVER['HTTP_FORWARDED_FOR'] || $_SERVER['HTTP_VIA'])
