What's the difference between an URL Type and an URL Scheme?

Question

Does anyone have a good explanation of that?

Answer 1

They're the same thing.

But here's how they might mean different things:

For example, iTunes uses the itms:// scheme when in fact HTTP is used as the transport protocol, so you can replace itms with http and get the same results. Similarly, feed:// is commonly used for RSS feeds, but the underlying transport protocol is still HTTP.

So itms and feed are not URL schemes in a strict sense. Their sole purpose is to trigger special applications (iTunes or an RSS reader).

I imagine Type and Scheme might be used to differentiate between schemes that correspond to a transport protocol, and those that don't.

Can you point out a particular resource that led you to believe they're different things?
