FWIW, here's "the" standard :) Section 4 basically says that a URI must start with a scheme, and a relative (URI) reference mustn't. So if you have "http:" at the beginning, you have an absolute (http) URI, and if not, it's a relative reference. In section 5 they define the resolution. I think you probably can extract a simple enough subset for your application to make simple appending, maybe with a very few conditional clauses, viable.
