Commented Certificate Chain Code

certificate-chain.coffee

# Require the https/fs modules
# Akin to Apache's configuration directive:
#   LoadModule ssl_module         libexec/libssl.so
#   (Apache's FS module is built in, I think)
https = require 'https'
fs = require 'fs'

# List the certificate chain files
# (with Apache you might put these 4 files into 1 file, called your certificate chain)
files = [
  "EssentialSSLCA_2.crt"
  "ComodoUTNSGCCA.crt"
  "UTNAddTrustSGCCA.crt"
  "AddTrustExternalCARoot.crt"
]
# Read these files (just like Apache does internally)
ca = (fs.readFileSync "/path/to/#{file}" for file in files)

# Specify the SSL configuration
# These are the equivalent of Apache's configuration directives:
#   SSLCACertificateFile / SSLCertificateChainFile
#   SSLCertificateKeyFile
#   SSLCertificateFile
httpsOptions =
  ca: ca
  key: "/path/to/server.key"
  cert: "/path/to/mydomain.crt"

# This is the thing that processes requests, i.e. this is the core of Apache.
requestHandler = (req, res) ->
  res.writeHead 501
  res.end()

# This creates a new instance of the HTTPS server, and then listens on localhost:443
# Akin to Apache's configuration directive:
#   Listen 127.0.0.1:443
httpsServer = https.createServer httpsOptions, requestHandler
httpsServer.listen 443, "localhost"
