Generating non-UTF-8 strings in ruby for testing
# It's sort of difficult to make a non-UTF-8 string in
# ruby that contains characters that aren't in UTF-8.
# Here's how I did it.
# 0x89 isn't allowed in UTF-8

A probably incorrect live-coded eTag example that doesn't use the eTag middleware
class StudentController < ApplicationController
def show
existing_etag = request.headers["if-none-match"]
student = Student.where(id: params[:id]).first
if(existing_etag)
type, id, modified = existing_etag.split("_")
if(type == student && id == params[:id])
if(student.updated_at == modified)
render :not_modified and return
