Can a link be crated that takes you to a difrent address depending on the address you are visiting from.
We have a work site that you can visit using a portal or directly if your connected to the work network. Now the problem is I'm visiting using the portal but the link I'm given is made for use by people who are connected to the network. I can get to the page using the portal if I navigated there my self but having the link be dynamic would remove that headache.
Sure it can, depends on how much access you have to the backend of the site you want to place that link on. Heck, it's probabaly even doable in pure JS ( ), but you'll still need access to the site's source code.
If it's just for you, write your own greasemonkey/tampermonkey script to overwrite the link target. Will not require any changes on the server and works for anybody with your script.
Tampermonkey example:
Code:
// ==UserScript==
// @name New Userscript
// @namespace http://tampermonkey.net/
// @version 0.1
// @description try to take over the world!
// @author You
// @match http://www.myworkpage.com/*
// @grant none
// ==/UserScript==
Signature/Avatar nuking: none (can be changed in your profile)
