Image caching problem

Morning all,

We're having an issue with images being cached for too long.

dest_domain=http://resources.mydomain.com      ttl-in-cache=60m

We have the above line in our cache.config file yet images that are being served from that domain are caching for a lot longer than an hour.

The images are all JPG and I'm wondering if using the suffix secondary specifier could help solve the problem?

Many thanks,

Andrew

Did anyone look into this? Can you make sure that your origin doesn't 
provide Cache-Control: headers which allows it to be cached beyond that 60m?
