A mirror is not a copy, it is a static snapshot. 
Anything that requires a webserver won't work with your collection of files.
This includes forms and non-self contained java applications.
You can not get asp or any other server side pages from the public side of a
webserver, only the html output.
If you're not getting everything, make sure you run with the near flag (get
non-html related files) so it gets everything even if they come from someother
site.
I always run with non external pages = checked, so you know where the mirror
ends and the internet starts.
