Add a TLS flag in RedisSessionStorage

[walkingbrad]

Overview

The implementation of RedisSessionStorage has no way of enabling TLS in the underlying Redis client it creates.

Type

• New feature
• Changes to existing features

Motivation

What inspired this feature request? What problems were you facing?

Heroku requires that non-hobby (i.e. production-ready) Redis instances always use TLS, so it's impossible to use RedisSessionStorage with Heroku Redis in production.

It effectively hard-codes this:

client = createClient({
    url: dbUrl,
})

where it should allow another flag to be passed such that we can create the client with TLS like this:

client = createClient({
  url: dbUrl,
  socket: {
    tls: true,
    rejectUnauthorized: false,
  },
})
