sdball / ezproxy_redirect.php
Created March 1, 2013 17:16
Some old PHP code I wrote to have PHP force EZProxy into being more secure.
<?php
/**
* ezproxy_redirect
*
* EZProxy requires that the username and password be passed via GET.
* This is just about as insecure as possible.
*
* So, we trick ezproxy into security by opening a socket connection
* to the server; acting as a browser to initiate the connection; then
* writing out its response to the actual browser.

Snippets from an old PHP IP Database I wrote. My hand rolled framework code was kind of nice.
<?php
// page setup
require('/www/includes/ipdatabase/ipdb_page.php');
$javascript = '<script type="text/javascript" src="/ipdatabase/js/index.js"></script>';
$page = new IPDB_Page();
$page->title('Main');
$page->javascript($javascript);
