During the latest Varnish Sumffffmit in London, the awesome Thijs Feryn had a presentation in which he explained the need to normalize Accept headers, and I proudly spoke up to say that a few weeks prior, I actually wrote a VMOD to do exactly that.

Well...I DID write it, but never actually blogged about it, being the procrastinator that I am. You can consider this post as a cathartic mea culpa, and as an attempt to give a bit more exposure to a VMOD that should have been advertised/used weeks ago. But enough self-flagellation, and let's look at this VMOD, after we explain what Accept headers are. If you are already fluent in that subject, you can skip ahead to the "Balls to the walls" section.
