Browser Caching Not Working

Hi,

I am attempting to get my browser caching to work and for some reason, it will not work. I’ve SSH’ed into my server and enabled the expires module:

Loaded Modules:
 core_module (static)
 so_module (static)
 watchdog_module (static)
 http_module (static)
 log_config_module (static)
 logio_module (static)

From there, I went in and auto-enabled the plugin, which created this in my .htaccess file:

# dynamically generated, and should only be modified via WordPress filters.
# Any changes to the directives between these markers will be overwritten.

</IfModule>
# END WP-HUMMINGBIRD-CACHING

From there, I cleared all my cache, enabled and disabled the caching, and still no success. Does anyone have any advice?
