I'll admit I'm not full y up on this, just copying a known working
example. For the gifs that MRTG creates, the .meta file has the single
line with the Expires: header in it, as listed above.
If you set the Expires header to something like 1 second past when the
gif is sent, Netscape should rerequest it each time.
The apache website has documentation on the cern_meta module at
http://www.apache.org/docs/mod/mod_cern_meta.html , and this references a
site at w3.org at
http://www.w3.org/Daemon/User/Config/General.html#MetaDir - basically, it
allows you to insert your own headers so something being sent out.
