A Detailed Explanation of the Anatomy and Components of a DotNetNuke Website URL
From the blog:
People don’t like to think about or talk about URLs. Unless someone know how their website works in detail, there is a chance for URL confusion. Even technically-minded people gloss over when talking about the details around what is happening with the fundamental pieces of a URL.
Because this seems so common, I thought I would devote some time to discussing each piece of the URL and what the significance is. The example used is a DotNetNuke (DNN) URL. I will start with the very basic and expand from there.
