title: Determine if a Url is absolute or relative from vb
body: <p>I'm trying to determine in vb if a URL is absolute or relative.  I'm sure there has to be some library that can do this but I'm not sure which.  Basically I need to be able to analyze a string such as 'relative/path' and or '<a href="http://www.absolutepath.com/subpage" rel="nofollow noreferrer">http://www.absolutepath.com/subpage</a>' and determine whether it is absolute or relative.  Thanks in advance.</p>
