[users@httpd] mod_proxy and caching
Hi all,
I am using Apache 2.0.48 on Windows 2000 with mod_proxy to reverse proxy to a number of back-end servers.
The Apache box is configured with basic authentication enabled, and it then forwards the credentials to the back end servers.
The link between the front-end Apache box and the back-end servers is not as fast as it could be, so I'd like to have Apache cache as much content (images etc.) from the back-end servers as possible.
However, am I right in thinking that mod_cache will not cache any resources where authentication is involved.
If so, is there any way around this - can I tell mod_cache to still cache *.gif, *.jpg etc. even though they may be protected with authentication?
Failing that, could I have authentication enabled for all files apart from images?
I've used:
<Proxy *>
AuthName "My server"
AuthType Basic
[...]
</Proxy>
to force authentication for all proxied resources - how could I turn authentication off for particular file types?
Many thanks,
John

One solution might be to simply host the image files on the front-end
server, and use an alias to the images folder; that way, all of the image
paths will resolve to the front-end rather than the mid-tier... (I haven't
actually tried this, but the connector on the Tomcat (with the ProxyName
=http(s)://front-side.com and ProxyPort=80/443) should support it with no
qualms..)
It might be a little difficult for the developers to understand, but unless
they are using absolute paths ( ./images ) you don't' need to tell them
(just copy the image directory over, edit the conf, and restart) :-)
