If-Modified-Since is also missing
Do your responses have a Last-Modified? If not there isn't anything to relate If-Modified-Since to..
So I have now no idea, why the static content is cacheable, but not my dynamic.
What does the cacheability check engine say about your dynamic content?
Is it not possible, to cache dynamic content ?
There is no difference in caching as such. Most dynamic content however does not have any information telling how long it may be cached or when the content was last modified so caches assume the content is dynamically generated for each request and should not be cached..
For something to be cached caches must have some reasonable means of knowing the response may be reused for another request. The Expires/Last-Modifed/Cache-Control max-age response headers play a crucial role in this. In addition your refresh_pattern rules is used when no explicit expiry is known (Expires/max-age)
