1) First problem is starting at
<http://auto.howstuffworks.com/stirling-engine.htm>. That is actually a
directory (there's a stirling-engine.htm/printable.html) This confuses HTT on
update and it purges the entire mirror on update. Mirror stirling-engine1.htm
instead.

2) Second problem is windows can't handle such large file paths:

Sure it does, upper right hand corner is a link titled "Random" That link can
redirect anywhere. On my mirror I don't have fig-wasp but I do have
insets/ants-bees-wasps.htm
Try adding a filter -*/random-article

3) With the changes above I was getting over 5GB before I canceled it. Picking
a random mirrored page I found:

Obviously %e1 is broken.
