redirect http to https

redirect http to https

upgrade normal sesions to secure sessions when possible

[micahstubbs]

will have a go at this one

[micahstubbs]

strategy:

• test by spinning up a second blockbuilder-frontend server
• point a subdomain I control at that new server
• get a cert for that subdomain + new server combination
• setup nginx as the web server
• use nginx settings to redirect http to https

once all is well on the blockbuilder-frontend-2 test server

• setup nginx + http to https redirect on the blockbuilder-frontend production server

alright, got my test server working, serving blockbuilder with nginx 🎉

you can check it out at http://blockbuilder.micah.fyi

(and watch the browser upgrade the connection from http to https)

[micahstubbs]

will try out this test server for a bit before switching over the main server.

@enjalot want to take a look at http://blockbuilder.micah.fyi, see switching to nginx breaks anything?

[enjalot]

looks like its in good working order to me. nice job getting a test server running!

to remove IPTABLES rules:

sudo iptables -t nat -D PREROUTING -p tcp --dport 80 -j REDIRECT --to-port 8889
sudo iptables -t nat -D PREROUTING -p tcp --dport 443 -j REDIRECT --to-port 8443

following this answer: https://stackoverflow.com/questions/10197405/how-can-i-remove-specific-rules-from-iptables

(we want to remove the IP Tables rules since we will use nginx going forward, since nginx makes it easy to redirect http to https)

ok, redirecting http to https

1: No redirect - Make no further changes to the webserver configuration.
2: Redirect - Make all requests redirect to secure HTTPS access. Choose this for
new sites, or if you're confident your site works on HTTPS. You can undo this
change by editing your web server's configuration.
