This bug (or my mistake?) also occurs in Version 3.15:
------------------------------------------------------

When including a file with a list of URLs, HTTTrack adds 
cryptic fragments of local system information to the URL!

For example, with a file "urls.txt" that contains a single 
line:
<http://localhost/manual/index.html>

and HTTTrack invoked by:
httrack -%L H:/_ht/urls.txt

the download fails giving the following hts-log.txt.
Look at the distorted URL after the 403 error!

------------------------------------------hts-log.txt-------

---------------------------------------------------------

The portion of the cryptic string varies if one inserts 
blank lines above the URL in urls.txt. So with some luck, 
if the URL eventually doesn't get distorted (let's say with 
7 empty lines above) the download works as it should!

Is it possible to fix that?
Kind regards,
Frank
