Hello,

On my server apache mod_expires is enabled.
On admin tools, ExpiresDefault option is activated (see below in red).

I made a small test and some expire header are not set (see attached file).
Do you know why I get no expires on some ressource like GIF (see attached file) ?

However, GIF expire is correctly defined in .htaccess generated by admin tools.
How is it possible to update default admin tools configuration?

Do you have any advice on expire headers use with admin tools?

Thanks
Laurent

on debian system, the module loaed is called like this :

LoadModule expires_module /usr/lib/apache2/modules/mod_expires.so

and not with mod_expires.c (in RedHat system)

maybe this is the issue?

see attached file.

ok so what can/should I do?

I am my own sys admin because this is a dedicated server.

I'm not using server cache from Joomla and there is no reverse proxy defined in apache configuration :-/

In apache configuration file, module is loaded :


# Activation du mod_rewrite

<ifModule mod_rewrite.c>

RewriteEngine On

</ifModule>



# Activation du mod_expires

<ifModule mod_expires.c>

ExpiresActive On

</ifModule>
