Up to this point, we've built a few usable applications; things we can start with and leapfrog into real systems for everyday use. By doing so, we've been able to demonstrate the basic and intermediate-level patterns involved in Go's concurrent syntax and methodology.
However, it's about time we take on a real-world problem—one that has vexed developers (and their managers and VPs) for a great deal of the early history of the Web.
In addressing and, hopefully, solving this problem, we'll be able to develop a high-performance web server that can handle a very large volume of live, active traffic.
For many years, the solution to this problem was solely to throw hardware or intrusive caching systems at the problem; so, alternately, solving it with programming methodology should excite any programmer.
We'll be using every technique and language construct we've learned so far, but we&apos...
