Re: Re: Cutting Out Previously Visited Web Pages in A Web Spider

There's no need to use URI::URL. Change the HTML::SimpleLinkExtor code to return absolute instead of relative paths.

There is a comment in my code in my last reply noting that my code currently returns relative paths and pointing you to the module docs. RTFM :-)

If the information in this post is inaccurate, or just plain wrong, don't just downvote - please post explaining what's wrong.
That way everyone learns.
