** Redirects

Permanently redirect from web root to specific URI:

<example>
location = / {
    rewrite ^ /sympa/ permanent;
}
</example>

** Blocks

Stop the POST flood to =/autodiscover/autodiscover.xml= generated by MS Office/Outlook:

{{{
location ~ ^/[aA]uto[dD]iscover/autodiscover.xml$ {
        return 403;
}
}}}

** Checks

=nginx -t= checks the configuration and =nginx -T= shows the complete
configuration in the order nginx processes the configuration.

** Performance Measurement
