We have been experimenting with a new reload, which only force revalidates the main resource (rather than all subresources).

+toyoshim who is working on this feature.
Apply Cache-Control: immutable ( issue 611416 ) for all subresources by default? too aggressive IMO.

Reg #2.

No, originally Chrome sent 'Cache-Control: max-age=0' for all resources in reloads. This was too aggressive today because now developers have the Inspector as a right tool to debug the web.

After the modification, Chrome sends it only for the main resource, but just follows the protocol for sub-resources. That means Chrome will uses cached contents only when the cached contents are allowed to be reused, e.g. not expired.
 Issue 662007  has been merged into this issue.
Hi, as I mentioned in

this is a significant nuisance when developing on localhost. Please consider fixing this.
