NAME
       mrtg-webserver - hints for web server configuration

SYNOPSIS
       If you want people to actually see the results of your
       network monitoring efforts you will need a webserver.

       This document lists some configuration hints for web-
       servers. Contributions welcome.

APACHE
       Configuring mod_expire

       A big issue with mrtg monitoring data is the expiry time.
       All these nice graphs you can create are only valid for a
       short time.  If you do not take special action some web-
       browsers will not notice this and you may end up with peo-
       ple seeing old data because of caching issues.

       The apache module mod_expire allows you to setup special
       expiry properties for individual file.

       Here is an example for how this may look for an mrtg web
       directory.  The configuration directives can be stored
       into a .htaccess file.

        ############################################################
        # Example .htaccess for use with apache-1.2 and mod_expire.
        # (mod_expire come with apache-1.2 but you have to explicitly
        # activate it when compiling the httpd ...)
