[rrd-users] RRDTool Graphs

Greetings all,

	This is probably off-topic, but I have no idea where to look for
this.  I have a number of scripts that use MRTG to create .rrd's and then
rrdtool to generate graphs on the fly and display them on the web.  This all
seems to work pretty flawlessly until it's displayed on the web.  Currently,
the graph files use the same name (day.png, month.png, etc)...  The problem
is, everytime I move to a new graph, it displays the old graph files unless
I do an explicit reload...  I've tried adding the following 3 tags to the
html :

<META HTTP-EQUIV="Pragma" CONTENT="no-cache">
<META HTTP-EQUIV="Cache-Control" content="no-cache">

But, these don't seem to do what I want..  Is there any way to force a
browser to reload the images every time?  This is very frustrating...  :(

	BTW...  is there a new version of RRDTool due out anytime soon?
Just being curious :)
