Seems like a basic question, but I couldn't find it 
elsewhere in the forum, so apologies if this is a FAQ.

I have a list of URLs in a text file that I test regularly 
to ensure they are still valid.  I am not interested in 
actually downloading the files the urls point to -- I just 
want to see that the URLs in the file haven't gone 404.  
I've been using HTTrack for mirroring for a long time, but 
this is different, and I can't figure out how to do it!  
If I use --testlinks, I still download copies of the pages 
the links go to.  Is there a way that I can tell HTTrack 
to stop downloading once it's clear that the URL goes 
somewhere?
Any advice?
