I have the following:

  fwtk from TIS,
  NCSA's WWW server, configured as a caching proxy
  Netscape 2.0 on a PC

Given this combination and given that I'm using the NCSA stuff rather than
the fwtk's http proxy, as I want the caching, I can't download anything
via ftp etc.  Seems to work on the Suns ok (Solaris 2.3/2.4) which confuses
me completely.  

Can anyone offer me any insight on this ?  Further - I thought that the
caching facility on the WWW proxy would have made access almost instant once
a page had been cached.  Doesn't seem to .. still seems to try to connect to
the site first - is that what's expected ?  Is it because of the expiry thing?

Thanks for your help,
Danny
