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	webservers.
       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 webbrowsers	will not notice	this and you
       may end up with people 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 ...)
