ASP.Net (101)

Token based authentication is a fairly common way of authenticating a user for an HTTP application. However, handling this in a load balanced environment has always involved extra caring. In this post, I will show you how this is handled in ASP.NET Core by demonstrating it with HAProxy and Redis through the help of Docker.

.NET Core Runtime RC2 has been released a few days ago along with .NET Core SDK Preview 1. At the same time of .NET Core release, ASP.NET Core RC2 has also been released. While I am migrating my projects to RC2, I wanted to write about how I am getting each stage done. In this post, I will show you the tooling aspect of the changes.
