  • Discovered challenge: Sa 14:05

  • Solved: ?

Challenge 7: Tech issues / SSL

There are a multitude of issues when serving the appcache manifest via HTTPS in a development environment. We wanted to test the features with SSL, to be as close to a "real" environment as possible.

  • Chrome does not accept the cache manifest when using a self-signed SSL certificate
    • Not even with chrome:/flag configuration "#allow-insecure-localhost"
  • Firefox requires manually adding the certificate authority

Challenge 8:

The major browsers might remove the appcache feature in the future as they want to replace it with service workers. So the challenge is to change the concept of this module.

Steps to solve:

  • Have a valid certificate (Create a key, create certificate, sign it yourself etc. , example: https://www.akadia.com/services/ssh_test_certificate.html)

  • Note your CA (Certificate authority)

  • Add it to your webserver´s virtual host

  • Add it to your devmachine Trust store (e.g. on Mac Os "Key store").

  • Set Firefox to use your machine´s key store (about:config security.enterprise_roots.enabled to true) )

  • Manually force Firefox to accept your CA: (Preferences > Privacy & Security > Certificates > View Certificates > Authorities > Find your CA > Edit Trust > This certificate can identify websites)

  • Discovered challenge: Fr 23:00

  • Solved: Sa 13:45
