   Yes. the cache control header is removed - https://github.com/apache/trafficserver/blob/master/plugins/esi/esi.cc#L1111
   
   We can either add an option to stop it from happening. 
   Or you can use header_rewrite / lua plugin to add the cache control header back at the "send response header" hook.
