Too many redirects error when logging into multiple apps

Ran into an error trying to log in, specifically to the inrupt.net provider.

To reproduce, I logged first into develop.generator.inrupt.com using my jmartin.inrupt.net pod, then logged into localhost as the same pod. The first login was successful (and showed the login form on the provider as expected). The second login immediately showed a Chrome error, reading:

This page isn’t working
inrupt.net redirected you too many times.
Try clearing your cookies.
ERR_TOO_MANY_REDIRECTS

Clearing my cookies did indeed help, but I was able to reproduce this error a second time.

首先重現登入流程：向 develop.generator.inrupt.com 進行驗證，然後使用同一個 pod 向 localhost 進行驗證，並觀察 inrupt.net 上的重新導向迴圈。將該流程與清除 cookie 後的登入進行比較，並確定哪項變更可以在維持跨應用程式成功登入的同時防止重複重新導向。
