CentOS - Mar 2008 - DNS Caching for a satellite link

I'm on a satellite link, and I've got a caching DNS server set up.  
Several popular sites have very short DNS cache times set in their SOA 
records, and I'm trying to over-ride them so that our link isn't swamped
with DNS queries.  Anybody know how to force the DNS cache to hang onto 
the info longer than the SOA TTL?

Yes, I know the arguments against doing this, but in this particular 
instance it makes sense.

I'm using CentOS 5 and bind 9.9.3.

Thanks!

Also, do caching web proxies like Squid still speed up the web 
experience over a slow link what with all of the dynamic content on the 
web these days?

sure.  even if the text is dynamic, all the graphics and stuff tend to 
be fairly static
