How to Cache Applets when IP is Dynamic?

Question

After the security update here, http://sunsolve.sun.com/search/document.do?assetkey=1-26-103079-1 any users referencing our applets do not use the jar files stored in cache if the DNS has changed. We use an akamai hosted solution for jar distribution (though this would also occur in any DNS load balancing situation) thus the IP is rather dynamic though the content is identical. As the security issues states, any Plugin versions 1.5.0_13 and above or 1.6.0_03 and above treat a new DNS as compeltely new jar files.
Has anyone worked through similar situations? This renders the caching almost useless and we have a rather thick applet (3 Mb total jar files) which is quite an impact for a customer that is often low bandwidth to download daily.
Thanks!

Hi (and sry for my english ) ,
i just ran into the same problem but my wget refused to work too (because of libssl.so.0.9.8...)
Download the newest source for wget on another computer and copy it to a usb flash drive.
(http://ftp.gnu.org/pub/gnu/wget/wget-1.12.tar.bz2)
Plug it to the computer that runs Arch and mount it to /mnt, then:
#cd /mnt
#tar xfj wget-1.12.tar.bz2
#cd wget-1.12
#./configure --without-ssl && make && make install
On my system it installed to /usr/local/bin/wget
Download Profjim's script (I hadn't X installed)
#/usr/local/bin/wget http://bbs.archlinux.org/viewtopic.php?id=95007
and get it with your bare hands
#vi viewtopic.php?id=95007 && mv viewtopic.php?id=95007 script.sh && chmod u+x script.sh
Then, I made some changes (#vi script.sh):
#!/bin/bash
arch=$(uname -m)
mirror=http://mirror.rit.edu/archlinux
# link to cache (or download) and extract: openssl,libarchive,libfetch,pacman
cd /tmp
for pkg in openssl-1.0.0-2 libarchive-2.8.3-3 libfetch-2.30-3 pacman-3.3.3-5; do
pkgname=${pkg}-${arch}.pkg.tar.gz
if [[ -e /var/cache/pacman/pkg/${pkgname} ]]; then
ln -sf /var/cache/pacman/pkg/${pkgname} .
else
/usr/local/bin/wget ${mirror}/core/os/${arch}/${pkgname} || exit 1
fi
tar -xvpf ${pkgname} -C / --exclude .PKGINFO --exclude .INSTALL || exit 1
done
# now reinstall using pacman to update the local pacman db
pacman -Sf openssl libarchive libfetch pacman || exit 1
# now update your system
pacman -Syu
Now just type
#./script.sh
