Doesn't the cache verify the last mod times of the remote URLs?
If configuring the max-age=0 is there still functionality in the caching or will it continuously expire?
How can we control the headers in the source server?

How do you expect the proxy server to find out about the updated
files?  There is no built-in way to do this.  You can trigger it
yourself by making http requests to the proxy for the appropriate URLs
with appropriate headers like
Cache-control: max-age=0
