Let's say there used to be a site called roachpeople.com. It ran forum
software, but the owners sold the domain name three years ago.  The forum and
its contents are now on newroach.com.

The issue I'm having is that all linked images on the site that are older than
three years are referring to the old URL.  The content is still in place, but
the references are using the old domain name. 
<http://roachpeople.com/pics/a/awesome.jpg> is actually available at
<http://newroach.com/pics/a/awesome.jpg>, but HTTrack doesn't know that.

Is there an option for HTTrack to substitute a URL in certain instances before
attempting a retrieve?
