The link must be a "persistent" link. This means that the link is not generated with a session identifier. When in doubt try it, but test it a day later to make sure it still works.
You do not need to do this for freely available sites (such as Google) or links that already begin with http://login.proxy.kumc.edu....
If you have addresses such as http://someaddress.com.proxy.kumc.edu..., this will fix them for you.
The links generated will work from both on-campus and off-campus.
