http_relative_path(+AbsPath, -RelPath)

Convert an absolute path (without host, fragment or search) into a path relative to the current page, defined as the path component from the current request (see http_current_request/1). This call is intended to create reusable components returning relative paths for easier support of reverse proxies.

If ---for whatever reason--- the conversion is not possible it simply unifies RelPath to AbsPath.
