SSL caching and redirects in chrome

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.

bye bye http - hello letsencrypt

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/

Corporate Firewall - SSH and port 443 goodness

Things you’ll need; (basic instructions) SSH - either Linux or Open SSH for windows (set this up first and ensure its working!). I have only used Linux, so i do not know the details of setting up a Open SSH box on windows (good luck).

Router with pinhole or port forwarding abilities. – forward your external 443 port to internal 22 on your SSH box

Putty.exe - use this to test your SSH connection locally (you should be able to connect on port 22 locally or 443 externally)
