[mrtg] MRTG and web page refresh

We are linking over the page via a 'naked' graph page.  I have the
following enabled in the router2.conf file:

# set to +2d if you want all autorefresh pages to work
auth-expire = +2d

# Normally, graphs refresh automatically as soon as they become out of date.
# This is about every 5 mins for daily graphs.  You may wish to make the
# minimum refresh time larger to prevent too-frequent updates
# integer in SECONDS, default is 0
minrefreshtime = 300

Am I missing anything here?

> The routers2 autorefresh depends very much on how the page is generated.  How are you linking in to Routers2 from the external pages?  If it is by using embedded images, or a 'naked' graph page (no header or menu) then the autorefresh is either not possible or is disabled.  If you are using the URLs generated by clicking the 'bookmark' button, however, the generated HTML should autorefresh at the appropriate frequency (the refresh code is hidden in the HTTP headers of the graph pane).  Otherwise, you'll need to code the HTML to refresh yourself.
