I'm trying to mirror a site where the server has a bug that causes it to
randomly return 404 errors. The pages actually do exist if you refresh. My
best guess is that perhaps the server is actually a group of servers behind a
round-robin reverse proxy, and that not all of the servers are synchronized to
serve the exact same content.

Unfortunately it seems that HTTrack does not retry upon receiving a 404 error
and it simply considers the link to be a dead end. Additionally, the system
administrator of the site I am trying to mirror is unable to fix the problem
at this time for bureaucratic reasons.

Is there a way around this?
