   The reason of remove these headers is?
   
   I can access and copy the "Cache-Control" header as "X-Cache-Control" during TS_LUA_HOOK_READ_RESPONSE_HDR hook.
   However, if i restore the "X-Cache-Control" as "Cache-Control" during TS_LUA_HOOK_SEND_RESPONSE_HDR. it will be removed. ( Although I can restore at the upper layer) 
   
   However, the age header seem can not access by ts.cached_response.header / ts.server_response.header in lua plugin. I think it is useful for multiple layer caching.
   
   Temporarily, I am trying to add a timestamp header to calculate the age.
