Control.ResolveUrl versus Control.ResolveClientUrl versus VirtualPathUtility.ToAbsolute

Question

Is there any benifit to using one of these methods over the other when resolving paths which start with the tilde (~)?

Generally, what is a better practice, should you be sending relative paths or absolute paths down in your html?

Answer 1

The difference between ResolveUrl and ResolveClientUrl is that ResolveClientUrl returns a path relative to the current page, ResolveUrl returns a path relative to the site root:

I would recommend using absolute paths.

Edit: Rick Strahl posted a nice article about this

Edit2: Removed bit about caching. Does not add to the answer and may not necessarily be accurate.
