If the url works in the browser then httrack can mirror it.

Remember that a mirror is NOT a copy. Server side code (SQL, PHP, CGI, ASP
etc) can not be seen from the public side of a web server, just the html
output and related files (images, css, etc.)

Mirroring your own site is useful with No Error Pages/No External Pages. That
way you can search the html output for external.htm/external.gif and you know
you have bad links in the original.
