Would push serve your needs? You could prepush content either as it
changes or once every day or so.

The Squid push branch is available as a CVS of its source code from
sourceforge.
Here is how to get a copy:

  cvs -d:pserver:anonymous@cvs.devel.squid-cache.org:/cvsroot/squid login
     [blank password, just press enter]
       
  cvs -d:pserver:anonymous@cvs.devel.squid-cache.org:/cvsroot/squid co
     -r push squid

A basic level of tools (webpush) and documentation (doc/push.txt) comes
with
the branch.

When you read the documentation, keep in mind that the PUT and DIST
stuff passes our internal tests, but I wouldn't use the hints in that
branch
just yet. But your application does not sound as though it needs hint
caching.

Support, more advanced tools and documentation, and consulting help, are
all
available from pushcache.com.
