[users@httpd] How does mod_expires handle proxied Cache-control content ?

Hi all ,
I have an Apache 2.0 Reverse Proxy . One of my downstream servers is an IIS server with Expires Header set to 12 hours for content . I have Apache configured with mod_expires as so (3600 seconds = 1 hour) 

ExpiresActive On
 ExpiresByType image/gif A3600
 ExpiresByType image/png A3600
 ExpiresByType image/jpeg A3600
 ExpiresByType text/css A3600
 ExpiresByType text/javascript A3600
 ExpiresByType application/x-javascript A3600
 ExpiresByType text/html A3600
 ExpiresByType text/xml A3600

How does Apache deal with the proxied IIS content ? Does it leave the Cache-control : max age = 12hours ..or does it 
overwrite it with 1 hour ?

Regards
Daniel

http://httpd.apache.org/docs/2.0/mod/mod_expires.html

according to this, mod_expires only affects setting headers when sending
local documents, it has nothing to do with proxy.
