Here's the deal: I do freelancing jobs at odesk.com and I want to track transitions from my profile or the job applications that I left to my personal website.
For clients the url of the job application page is https://www.odesk.com/applications/xxxxxxxxx, where xxxxxxxxx is the id your job application.
So I thought I would just use $_SERVER['HTTP_REFERER']
to retrieve the previous url and take the job application id from it.
But guys from oDesk first redirect you to a page like this: https://www.odesk.com/leaving-odesk?ref=yyyyyyyyyyy. And only then users get redirected to my website.
My question is: is there any way to know from which page (which job application) the visitor of my website came?
