Grattpd: the world's best (GScript) web server

3.7 Using a PHP gateway to access your site
The problem with using this setup is that your website's port will change periodically. To combat this problem, I've written a PHP script for Era's website which allows you to visit http://graalcenter.org/ and be redirected to the current site. It also redirects requests for specific pages, so that you can link to http://graalcenter.org/some/random/page and know that it will always work.

The PHP code I used for this PHP gateway is:

index.php

PHP Code:

<?php
$fh = fopen("port.txt", "r");
$port = fread($fh, filesize("port.txt"));
fclose($fh);

header("Location: http://server.era.graalcenter.org:" . $port . "/" . $_GET['go']);
?>

update.php

PHP Code:

<?php
$pass = "change_me";
$ip = "50.23.136.183"; // get this from statistics.graal.us

if ($_SERVER['REMOTE_ADDR'] != $ip || $_GET['pass'] != $pass) {
    die("**** off");
}

$fh = fopen("port.txt", "w") or die("aa");
fwrite($fh, $_GET['port']) or die("bb");
fclose($fh);
?>

.htaccess

RewriteEngine On

RewriteCond %{SCRIPT_FILENAME} !-f
RewriteCond %{SCRIPT_FILENAME} !-d
RewriteRule ^(.*)$ index.php?go=$1 [QSA,L]

Be sure to change the password and the redirect URL. You can then enable it in http_listensocket.

4. Conclusion
I think I've covered everything. The script is attached as a ZIP file to the post above. If you have any questions, feel free to ask. Comments are also welcome.

You can see an example of Grattpd in action at http://graalcenter.org/ (note that the site is unfinished).
