[CentOS] mirroring with lftp

i've maintained a local centos repository at work using rsync, but it 
seems the corp honchos have decided to block rsync at our firewall, plus 
its never been 100% reliable, I'd get aborts on protocol errors 
sometimes several times before pulling down a complete new distro update.

i'm trying to figure out how to do this with lftp, and its got me 
somewhat stymied.


I'm testing with --dry-run like...

     lftp -c 'open http://mirrors.kernel.org/centos/ && mirror -c -X 
\*/ia64 -X \*/s390 -X \*/alpha -X \*/SRPMS --dry-run'

but my -X excludes don't seem to work (I don't want/need itanium, s390, 
alpha, or SRPMs in my repo).

and, it doesn't seem to be aware of the symlinks from, for example, /5/ 
to /5.6/  and seems to want to pull down two copies instead (I 
understand that http doesn't make symlinks obvious).  Should I use 
ftp:// instead of http:// or something?


does someone have a script for maintaining a repo with lftp they'd like 
to share?   what I saw on the wiki wasn't very helpful.
