// version 0.01.
// Date: 2005-08-25
// Copyright (c) 2005,2006,2007,2008 Andrew Perry
// Released under the GPL license v 3 and higher
// http://www.gnu.org/copyleft/gpl.html
// Modified to use redirects instead of url rewriting so that it works
// for the first page. Jonathan Hunt <jjh@42quarks.com>
// Modified slightly to work with NUS Libraries proxy by Aaron Tay
//
// YOU NEED TO EDIT THE VARIABLE proxyname (SEE BELOW) WITH THE DOMAIN
// FOR YOU INSTITUTIONS EZPROXY / LIBRARY PROXY ....
//
// Notes:
// Ezproxy (http://www.usefulutilities.com/) is a common proxy program used by
// university libraries to allow access to subscription based full-text in journals.
// This plugin adds the proxy domain to outgoing links from journal sites 
// This allows users to automatically follow links through their institutional 
// library proxy for seamless access to journal fulltext (if they are subscribed). 
//
// Could be easily modified to work with other similar proxies like the CoralCDN ..
//
// This is a modified version of Library Ezproxy Forwader script by aarontay.
