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_ex - pire.
# (mod_expire come with apache-1.2 but you have to ex - plicitly
# activate it when compiling the httpd ...)
