The StackExchange sites are a collection of websites on various topics where people can ask questions and get answers from members of that community. People can also up-vote or down-vote both the questions and the answers, as well as add comments regarding either. People receive ranking points, called ‘reputation’, for asking questions and on how many up-votes/down-votes their questions and answers receive. It’s intended to drive an active (and interactive) community of people around each subject area. The first and most popular of the sites is StackOverflow.
Sometimes it can be a huge pain in the rear to work with SSL on local IIS or IIS Express in Visual Studio. I was trying to debug an issue with my authentication flow and just could not get my auth server to run locally. I finally came across this StackOverflow answer and discovered that I was running into the issue where my port for IIS Express was something like 66234. I didn’t know that to get it to work right, you have set the port between 44300 and 44398. And like Jason’s answer, absolutely nothing I could see either during setup or runtime told me that.
