Forward HTTP requests to HTTPS

I've set up my Sage server to run on a public-facing interface and with the 'secure=True' option. I'm also forwarding port 443 to this secure server. This works reasonably well, except that the only way to access the server is with an explicit "https://" (no port number required since I'm forwarding 443). I'd like to just be able to type my hostname (without the protocol) and be automatically redirected to the secure portal. Is there some way to configure the underlying web server to do this?

This is somehow unrelated to Sage, you need to have a webserver listening on port 80 that forwards to port 443.

For example, if you are running nginx, you can add the following in your configuration:

server {
    server_name your_hostname.net ;
    listen 80 ;
    location '/' {
        return 301 https://$server_name$request_uri ;
    }
}

We use that for the site ask.sagemath.org ;)

I'm using the sagemath-upstream-binary package from ppa:aims/sagemath, so I didn't explicitly install or configure any web server. What web server is used with that distribution, and where can the config files be found?

You can install the nginx ubuntu package, and put the previous lines in the /etc/nginx/sites-enabled/sageredirect file. That said, i am not sure that having Sage notebook directly listen to a public port is a safe idea, i would use a real webserver (like nginx) in front, especially if you plan to make the address public.

I see. So the notebook is itself a web server (not running on top of apache or similar). I just set up a basic nginx/apache web server that forwards requests to the sage notebook? Is that the basic idea?

Yes, the notebook is a itself a webserver (which is nothing but a program that listens to some port for http requests). Regarding using a bulletproof webserver in front as a proxy, this is what i would have done, though i have never set up a public notebook, so i encourage people that did it to withness about their experience here. You could also look at wiki.sagemath.org and look for some documentation about that.

There are several places on the wiki about setting up a public server, and the somewhat not used sage-notebook Google group. People have definitely set up proxies for the sagenb server, though, and pretty easily if you are someone who knows about how to do such things. It's not as modern as could be, but works out the box (hopefully still with Sage 8.0 too) for this purpose.
