In Outlook 2013, I could only give my credentials once, access to my main view, but once I closed the task pane and I wanted to relaunch the add-in, I was blocked on the loading.

I figured it was probably a problem with Outlook 2013 cache, and maxpaj's answer did the trick ! I added the cache control headers to my index.html file and problem solved :) So thank you maxpaj for saving my time !
