  Just login (telnet, ssh) and type "which gzip".  It will either
  say what it is (where/pathname) or "not found" meaning it is
  not installed...  Most of your Win.X software now comes
  "zipped" in one form or another - and most Win machines can
  "read" it, so the probability is very good here.  You might
  just put a "link" to winzip on your pages (with approval) and
  let people know that it, or some uncompress utility that
  understands gzip will be required...

  We all do in one way or another...

  Now we start getting "complicated".  Can you gzip a file and
  have it "download" - yes.

  Problem is, your message(s) imply that whatever you are talking
  about is being stored "un-compressed".  If you simply call gzip
  with a filename - it will compress "that" file, making it a
  "filename.gz" vice the original filename (eg: index.html
  becomes index.html.gz).  Now the problem becomes how to
  "compress" the original (but not the master copy of the file)
  and then make that available for download... and I do not have
  enough information about what you are trying to do to give any
  sort of detail on how to do it....
