APACHE

16   Configuring mod_expire
17       A big issue with mrtg monitoring data is the expiry time.  All these
18       nice graphs you can create are only valid for a short time.  If you do
19       not take special action some webbrowsers will not notice this and you
20       may end up with people seeing old data because of caching issues.
21
22       The apache module mod_expire allows you to setup special expiry
23       properties for individual file.
24
25       Here is an example for how this may look for an mrtg web directory.
26       The configuration directives can be stored into a .htaccess file.

31        # activate it when compiling the httpd ...)
