Prevent infinite reloading loop.

[cbilotta]

When a file in the public folder changes, the client will infinitely refresh.

This was handled in previous versions, but for some reason it broke.

In development, every time I change the main.js file the caching seems to fail, and the client infinitely refreshes. Is there a way to disable caching during development?

We normally send a HTTP 200 OK when browser don't get the HTTP 304. If you happen to reproduce this, some help on this issue would be appreciate.

It what probably fixed in 1.5.2, or will be in 1.6. Don't remember where I read this, but this is probably a gone problem.
