Make sure that your origin server is sending information that indicates the version of the objects so that the 
Edge server can send a conditional GET request when those objects expire.



Also make sure that your origin server responds properly to these conditional requests, with a 304 Not Modified, 
if the file has not changed since the time specified or if the ETag value specified still matches.

Advanced Functional Programming with Scala - Notes

Copyright © 2017 Fantasyland Institute of Learning. All rights reserved.

1. Mastering Functions

A function is a mapping from one set, called a domain, to another set, called the codomain. A function associates every element in the domain with exactly one element in the codomain. In Scala, both domain and codomain are types.

val square : Int => Int = x => x * x

These exercises were part of a LambdaConf Outpost meetup. You may find the instructions here.

1. Develop a model for boolean values (Bool), which may be either true or false.

   Think: Do you need an if-then-else construct? Why or why not?

   Bonus: Develop a model for eithers (Either), whih can be one thing ("left") or another ("right"), and model a boolean as a partitioning of a set into two disjoint sets.

2. Develop a model for optional values (Maybe / Option), which are containers that are either empty ("nothing" / "none") or hold a single value ("just" / "some").
