Re: 'content_class' of Field.FileField is OFS.Image.File instead of CMFDefault.File

| I have the problem that in plone files and images do not go through CMF's

| the caching policy manager, but http://myplone.org/big_file and 
| http://myplone.org/big_file/download do not, which means that for the big 
| files no caching header can be set easily). 

Use CacheSetup and PolicyHTTPCacheManager. CacheSetup patches
OFS.Image.File to use the a cache manager called
'HTTPCache'. PolicyHTTPCacheManager forwards requests for caching to
the 'caching_policy_manager'.
