I have just written a c program to extract urls from 
hts-log.txt.It grabs any url between two strings you 
specify, and saves them in a txt file.You have just to 
copy urlist.exe where hts-log.txt is and run it.A txt 
file, named urlist.txt, will be created at the same 
directory.

Can find it at <http://galeon.com/urlist/>
