You may encounter a direct resource (say a video in Swank) where you want to link to the direct resource, but the URL in the address bar looks like this (a Swank video in SJRSC's collection):
https://digitalcampus-swankmp-net.eu1.proxy.openathens.net/sjrstate363603/watch?token=8FBB85F808055AD1
A URL like this, if linked while not authenticated, routes the user to a generic OpenAthens "Where are you from" (WAYF) login where they have to pick their institution. It can be built to go through the campus SSO instead.
The yellow highlighted part of the URL contains both the platform (Swank) and the coding to route it through a generic OpenAthens WAYF. Everything after the slash is the actual video and perhaps a customer number in some platforms. To make this resource route to the video, but via your campus SSO to authenticate just replace that yellow highlighted part with your redirector and the platform access URL and leave the stuff highlighted in pink that designates the exact title. The URL then codes the same resource but tells it to go to your campus SSO via the redirector instead of a generic OpenAthens WAYF login So it becomes this:
https://go.openathens.net/redirector/sjrstate.edu?url=https://digitalcampus.swankmp.net/sjrstate363603/watch?token=8FBB85F808055AD1
