Default URL when launching jupyter server puts you in infinite loop

[yuvipanda]

1. Install jupyter_server
2. Run jupyter server
3. It opens a URL that's /?token=XXX in browser
4. This URL infinitely redirects to itself, never shows anything

If you manually have it open something like /voila?token=XXX it works fine. Default behavior should be better.

Does this happen only in Firefox?

@afshin chrome and firefox

(That is to say, I have no insight.)

Default behavior should be to not open a browser :-) #51

[yuvipanda]

@rolweber right, I agree :) However, it does go into an infinite loop even if I specify --ServerApp.open_browser=False, and copy paste the URL manually.

We need to come up with a suitable message for the welcome page.

• You're looking at the tail end of this headless server.

• Please move on, there's nothing to see here.

• Welcome! Please go away.

• Only robots allowed beyond this point.

It would make sense to have a tornado template for the a default page (like we have 404.html and 500.html), and have the redirection point to it by default.

• Someone launching jupyter server would typically end up at this URL unless they specified something else.
• Someone making explicit use of some ExtensionApp (after @Zsailer's PR is merged) will typically be redirected to the default URL.

A default page for the server makes the most sense to me.

We should also remove all the notebook templates in this repo.

Solved in #54

I'm going to close this for now since we added a default landing page in #54. Feel free to re-open if this doesn't fix things for you.
