I have a Symfony2 app using assetic. Everything is fine except that in localhost my assetic assets does not get cached by browser.
Any idea why the following assets does not get served cached with response 304 and in milliseconds but instead with 200 response and takes about 15 seconds....

Even if I go directly to this file through browser and then press F5 cache is not working.... But instead in other files i get 304 instead of 200...
assetic_use_controllerset totruein your configuration for assetic? That would force symfony to serve the request instead of the filesystem. – phpisuber01
