Mod disk_cache permanent caching images and disabling reacurring header updates
- by user135532
I am trying to get mod disk_cache to permantly cache images retrieved from an image server on the webserver using ProxyPass.
While the image is being retrieved correctly from the server and is served from the cache on further requests,
then I am still having the webserver call the image server and causing the cached header to be updated.
Because of load concerns then I need to never call the image server on a specific url again after it has been cached once, or extend the refresh time for as long as possible.
The webserver is IHS 7.0
The mod's are mod_disk_cache.so, mod_cache.so, mod_proxy.so Version 2.2.8.0
Following is from my httpd.conf:
ProxyPass /webserver/media/images/ http://imageserver.com/ws/media/images/

<IfModule mod_cache.c>
<IfModule mod_disk_cache.c>
