Hi,
my wishes:
- I want to give www clients to our users but I'm afraid because of the
  traffic (we have only 64KB bandwidth). 
- It would be nice if I could say
     xmosaic -cacheserver a_local_host:port
  and xmosaic would connect to a_local_host:port and write
  GET /host[:port/...      (full http URL without prologue http:/ )
- then I could create a cache server
  the first GET generate  a remote GET - the second can give the answer
  local and fast
- the I also need a HTTP command that gives me not the file but the
  needed information about the file like size, date etc. (is it HEAD?)
  So a cache server could implement refreshs ...

what I've done:
- to get the  nice GNN from nearnet.gnn.com, I've saved the home page
  to my local server and have created a link to it from my local root
  page
- this "cache" erver is a plexus and I've hacked in the dir.pl
  to do the job (craeting directories and getting the file and
  putting them to the clients)
  It runs on a separate port - the port number is my "mapping"
  to the mother server.

Are there other/better solutions to do such a job? How can I get 
infomations like filesize and date?
