Thanks for the reply. I have now removed the additional and unneeded ExpiresDefault. The FilesMatch is working without the tilde so it must be ok but I still dont get cache validation with the sub domains.
Can you explain a little more how I can check that the subdomains are supplying mime types?
One other point, if I use mime types to serup expires times, do I also need filesmatch as well?
