Does browsers caches target locations of request redirects? eg.
http://example.org/assets?ts=3248723642873 [302]
-> http://example.org/css/test.css
-> download
http://example.org/assets?ts=766773 [302]
-> http://example.org/css/test.css
-> from cache
http://example.org/assets?ts=saa766773 [302]
-> http://example.org/css/test.css
-> from cache
From my test i conclude that there are not but want to be sure.
