Coming from a background as a Windows developer, one of the biggest issues I faced when starting to build *nix apps was how to develop locally. Trying to develop a sails.js app or build a Varnish caching proxy on a Windows machine gets pretty fustrating pretty fast. Additionally even if you are running Ubuntu locally, unless you only work on a single project you’ll run into the issue of multiple apps needing port 80 for testing.

TL;DR; - Before V4.0.0 Varish ignored the “Cache-control: no-cache” header by default, and you’ll need to handle this yourself in your VCL.

With Google’s recent announcement of the “Turn Down of PageSpeed Service”, users of the service should be asking what to do next.

Last year our team gathered at an offsite to consider issues with current CDN providers and the problems with use of global content delivery solutions. We recognized the closed nature of the distributed networks available and at the same time identified the deployment and distribution limitations of the excellent opensource tooling required for content delivery clouds (such as Varnish Cache for HTML caching). These issues lead us to build section.io.
