Deleting Items and Flushing our Redis Cache

export default class RedisController {
    public async destroy({ response, params }: HttpContext) {
        await cache.delete(params.slug)

Hi codthing! Everything you've shared looks right. If you're viewing your Redis database with a GUI application, those often don't reflect live data and require refreshing in order for them to reflect changes made to the database contents. Also, make sure you're viewing the Redis database actually being used by your application! This can be found within config/redis.ts

const redisConfig = defineConfig({
  connection: 'main',

  connections: {
    main: {
      host: env.get('REDIS_HOST'),
      port: env.get('REDIS_PORT'),
      password: env.get('REDIS_PASSWORD', ''),
      db: 1, // 👈 indicates I'm using Redis DB1, DB0 is typically the default
      keyPrefix: '',
      retryStrategy(times) {
        return times > 10 ? null : times * 50
      },
    },
  },
})

You might also do a sanity check, just to ensure your controller methods are actually being hit correctly, by adding a console log to each.

//redis controller
export default class RedisController {
    public async destroy({ response, params }: HttpContext) {
        console.log('destroy', params.slug)
        await cache.delete(params.slug)
        return response.redirect().back()
    }

    public async flush({ response }: HttpContext) {
        console.log('flushing redis')
        await cache.flushDb()
        return response.redirect().back()
    }
}

If neither of those help, please feel free to share a link to your repository and I can take a deeper look to see if anything stands out!
