In our source, there are various links within the file (example):
<script src="//ajax.googleapis.com/x/y/z"></script>


httrack contents shows:
<script src=http://ajax.googleapis.com/x/y/z</script>

The site is fronted by a https server, so this results in mixed security
content.  Is there a way to copy the content as is, or make it default to
https?
