While setting up SSL reverse proxy using lets encrypt and nginx i had a few troubles with testing via googles Chrome browser.
Chrome caches some SSL responses which can be cleared by deleting your browsing data via settings or Ctrl+Shift+Del.
Chrome also caches http -> https redirects, you can see these by going to chrome://net-internals and select “HSTS” from the drop down. Enter the domain name under “Delete domain” and press the Delete button
The easiest thing to do during testing is use incognito mode. You will not need to clear the cache every time you change config or re-issue certificates.
I’ve been a fan of HTTP and caching since my dial-up modem.
Skip to today where google returns HTTPS sites higher in its search results. Its could also be possible that you cannot trust a man in the middle HTTP cache any longer either right? :)
SSL certs have traditionally been expensive, but say welcome to lets encrypt which provides a free way of securing all of your websites. If you haven’t heard of it check it out here – https://letsencrypt.org/
As always i’ve implemented my LetsEncrypt trial via docker. The container image i have been using has been put together by the linuxserver guys – https://hub.docker.com/r/linuxserver/letsencrypt/ (i use a few of their container images, they seem legit)
This container image comes ready to roll with Nginx built in which can act as a reverse proxy to your unsecured websites at the back-end. I’ll be testing it for the next few days to see how it stacks up, but so far so good. Nginx is fast, so a good transition if only to offload all my SSL traffic. If all goes well it will be the end of my squid reverse proxy which i have used happily for many years.
In the past http had the performance, certs were too difficult (but are they?) and expensive to implement and i was a fan of my sites being cached. New times are here, SSL (TLS) rules supreme.
On another note, HTTP 1 sites are dwindling, SPDY didnt last long but apparently some of that has been built into HTTP/2 – exciting!
