# .htaccess file for use by Apache with mod_expires.  Other web servers /may/
# also support this.  Put it in the graphs directory, and set the options in
# your httpd.conf to have AllowOverride set.
# We set the expiry time to be 1 second less than the lifespan of the graph
#
# Filenames will be <router>-<interface>-<time period>-<graph style>.<format>
# where <format> is gif or png
#       <graph style> is n, l, t, x2, etc etc
#       <time period> is 6,d,w,m,y with s for summary
