Pragma should not be sent out from a web server; this is for web clients
to communicate with servers/proxies.
You should send:
1. Cache-control: no-cache
2. Ensure no Last-Modified header (can't use ns_returnfile)
3. Add Expires: Thu, 01 Jan 1999 00:00:00 GMT (don't use a date like
1990; some browsers goof and ignore older dates; don't use this for
animated GIFs that loop, or Netscape will hit your server on each loop)
4. Generate a unique Etag: header for the truly paranoid
