I have to apologize for this misleading report. The actual situation is as follows: When a browser (here: konqueror) is pointed towards a munin page (for example http://localhost/munin/localdomain/localhost.localdomain.html), the browser issues a HTTP GET request with an "If-Modified-Since" header with the timestamp of the graph that was locally cached. The munin CGI replies with "304", causing the browser to display the outdated picture from its cache. When "Reload" is clicked, the browser issues the same request without the If-Modified-Since header. The munin CGI correctly sends the graph then. To me, this looks like a bug in munin's If-Modified-Since handling, which should be fixed. I can reproduce the bug on command, so I can help debugging, if that is desired.
